horpeyemmi66: 4. Let the distance from his starting point be x. So sin 30/5= sin 120/x x=5sin 120/sin 30. X= 8.7km. 5. Using pythagoras rule x^2= 12^2 + 5^2 x=13km. Which is the displacement. The total distance travelled is the sum of the distance he travelled in both directions which is 17km (12 + 5). So difference is equal to -4km. 6. D 7. B. Vectors have both magnitue and direction and every watchamacallit in option b does. 8. Impulse = momentum change. Ft= mv - mu. I believe the answer is 20kgm/s but using the formula gives something diff. Please kindly do extensive explanation here. 9. Is definitely A. 10. Tough but i think i'm tougher.. Hehe , F= ma right? No owo e so ke to ba n doubt. No hands up seems i can go on. 2000= 800 x a a= 2.5m/s/s. After the force was applied, the car moved with 2.5m/s/s before it completely stopped. The distance it took the car to finally stop should be uhm.. V^2= u^2 + 2as 20 x 20 =0 + 5s S = 80m. Apparently, option B is the correct answer. RIP to the dog. I can't remember the last time i read but the way things are(your questions pushing me), i'm sure it won't be long for me to re-marry my books. For the record,we're divorced. |

mikechibuzor: For the impulse Ft=mv-mu after hitting the wall the ball rebounded and moved in the opposite direction Ft=mv-(-mu) the - sign was introduced cos of the opposite direction 10+10= 20 horpeyemmi60 over to you 1 Like |

horpeyemmi66:1• P = A•P + Pwater Pk = 15 + 120 = 135m of Water Pc = 15 + 180 = 195m of Water Thus: Pc/Pk = 1.44 2• A•P Read By Pilot = 83cm of Hg= 0.83m of Hg A•P = 0.83 x 15000 (Conv. R•D of mecury i.e 15 to Density in Kg/m3) x 10= 124500N/m2 Thus: Distance between the Top Atmospheric Level and Aircraft 1.5(R•D of Air in Kg/m3) x 10 x h=124500 H = 8300m A•P Read by Ground Observer = 94cm of Hg = 0.94m of Hg A•P = 0.94 x 15000 x 10 = 141000N/m2 Thus: Distance between the Top Atmospheric Level and Ground Observer 1.5(R•D of Air in Kg/m3) x 10 x h=141000 H= 9400m Height of The Aircraft Above Ground Level = (9400 - 8300)m =1100m 3• A•P = 0.85m of Hg = 0.85 x 18.5 x 1000 ( R•D of Hg in Kg/m3) x 10 = 157250N/m2 Thus: Height of Water Column = 1000 x 10 x h = 157250 H=15.725m 4• If you really meant Distance = 13km but if it is displacement D^2=25+64-2(5)(8 )Cos120 =25+64-2(5)(8 )(-Cos60) =25+64+40 =128 D = 11.3 km 5• Magnitude Of Displacement = 13km Distance Travelled = 17km Their Diff. = 4km 6• C 7• B 8•A. 9• C 10• B |

Well, well, what can I possibly say, I have been so impressed by you guys from Mikechibuzor to thaotech to enry54...your attempts are so worthy of an applause. Basically, you chewed those questions...I want us to go over them again, so you can mark yourself. 1. There is a formula →Pabs= Ap + h For the first Submarine, The knight →Pabs= 15+120= 135 For the second Submarine, The cascade →Pabs= 15+180= 195 The ratio of the cascade to the Knight is given as Pc/Pk Therefore Pc/Pk= 195/135 →Pc/Pk= 1.44 2. enry54 had it solved well, but I'd have to go through another route. The said aircraft(Aneroid barometer) is obviously in the air and the observer is with a barometer(Mecury) on the ground. One can infer from that above that AIR= hρg AIR= h x 0.0015 x 10 AIR= 0.015h ON THE GROUND= (h2-h1)ρg ON THE GROUND=( 94-83) x15 x10 ON THE GROUND= 1650 Therefore, →0.015h=1650 →h= 110,000cm →h=110m 3. h1ρ1g=h2ρ2g obviosly, we are to look for h2 → h2=h1ρ1g/ρ2g when g cancels out →h2=h1 x ρ1/ ρ2....... recall from question that relative density/ Specific gravity of Mecury was given as 18.5 →ρ1/ρ2=18.5 Invariably, →h2= 0.85 x 18.85 →h2=15.73m 4. I want to draw an attention here, when using the cosine formula, one thing is considered, the Sign. The formula goes with a minus when Θ>90°, and with a plus when Θ<90°. I am not solving that question, you were asked to find the displacement although the ans is 11.36km when done correctly it's not the total distance they are asking after. I guess you should be able to do justice now. 5. No need to touch that...you all smashed it 6. D, cross check with S=ut+ 1/2gt^2 7. B 8. Thanks for the explanation at thaotech, that's just it. But the examiners could be silly and say the ball bounced 3times, 4times etc. The thing to do is, solve normally and multiply your final answer by the number of times the ball bounced. 9. C, why C abi....come along. X and Y cover the same distance, So, Sx=Sy but it was from rest then Uxt + 1/2axtx^2= Uyty + 1/2ayty^2 0+1/2axtx^2=0+1/2ayty^2 also, "the acceleration of X is twice that of Y" ax=2ay Substituting the relationship, 1/2• 2ay•tx^2=1/2•ay•ty^2 when 1/2 cancel out and ay follow suit then, the ratio becomes, 2tx^2=ty^2 tx^2/ty^2=1/2 tx/ty= 1/√2 10. I can see a couple of ways in which this question was dealt with...you can also go about it this way Workdone= Change in K.E F x D= 1/2mu^2-1/2mv^2 F x D= 1/2m(U^2-V^2) D= [1/2m(U^2-V^2)]/F when done correctly, D=80m(the vehicle actually did hit the poor dog which was 50m from the car's initial position). After hitting the dog, the driver stopped 80m-50m=30m after hitting the dog. It's not something terrible afterwards, the dog is now in Dog Heaven...lol! And btw, banking angle is something else oh, banking angle is that angle which a car, bicycle, motorcycle, turns through when negotiating a bend on a sloppy road or surface...it has a formula, but not needed in O-levels. Thanks for staying tuned! |

Keep it up guys, I'm following this thread for someone who also intends to get into UI, I must say from the level of preparedness I see here that, the Majority of you must make it, as it were I plead that any information about the procedure for the PUTME should not be kept. This is funny, I'm am actually a student of UI, but I also know that your wires are higher than ours when it comes to getting info, when in ui, u'll understand. (Books books n books). All we pride in is the experience we have gotten. With that said, I pray the Lord helps us. All. Are there DE applicants here? I have some experiences that might answer ur questions. |
