amen. but the method i hell no pray for, is jamb and o'level aggregate for post utme call-up. becus, i had credit all through in my o'level.
I'll rig for JAMB + Post-UTME combinations to be adopted!

Stephen, please check the ways you use your words...What's terrible about my life that I should see??

Biko!

I would pretend as though I didn't see that, because a brawl is the last thing needed now.

Sir Whales2020, 7/10, a pass mark...please see nos 1,2 and 5, well done.
The only reason why i'll honour this quote from you is nothing but the fact you quoted my moniker directly.

As for my words it was intended to be a soft jab not a brawl. But again i'm sorry it read something else to you!

Please next time use my moniker not my surname.

*PHYSICS
1. A car of mass 1000kg is moving up a hill inclined at 30 degrees to the horizontal. The total frictional force on the car is 1000N. Calculate the force P due to the engine when the car is moving with a steady velocity of 2.5m/s.

A. 5.9KN

B. 6.0 KN

C. 7.2KN

D. 6.0mN

2. A car of mass 15Kg is pulled up by a force at an angle of 30 degrees on an inclined plane which makes an angle 25 degrees to the horizontal. If the car moves at constant speed with a force of 50N acting against its motion, determine the co-efficient of friction.

A. 0.60

B. 0.63

C. 0.73

D. 0.91

No1. Since velocity is constant, net force=0
Resolving forces along the plane....
P=mgsin30 + 1000
P=1000P *10 * 0.5 + 1000
P=6000N=6kN

No2. The opposing force here = 50N which is equal to the resolved force on the body along the plane.
50N=mgsin25+umgcos25
But the ans is negative. I think the question is not correct. But going by the fact that the opposing force is the friction only, then from
F=umgcos25, since the a=0
50=135.95U
U=0.36
*which is not in the option. Pls check the question...

Not at all @Chimezie...you are getting it all mixed up.

Here you go:

RESOLVING HORIZONTAL FORCES PARALLEL TO THE PLANE

Fcos30-50-mgsin25=0

0.8660F-50-63.39=0

0.8660F=113.39

F=113.39/0.8660

F is invariably = 130.93N

RESOLVING FORCES PERPENDICULAR TO THE PLANE

Fsin30 + R= Mgcos25

0.5F + R= 150 cos25

(0.5 x 130.93) +R= 135.94

65.46 + R= 135.94

Therefore, R= 70.48

Recalling Fr=₹R.............Where ₹=co-efficient of friction.

₹=Fr/R

₹= 50/ 70.48

₹ = 0.709( closest to 0.73 in the question)

That was a very good attempt I must add. You noted all the rudiments of the question.

That's very good I must say!.... I misconcepted the of 50N. Because the total force that oppose the motion should be sum of the forces in the opposite direction to the force parallel to the plane in reference to the body. #kudos

It seems u re good in recalling names but just stick to P0lymath.
