A car’s engine produces a useful output power of 6.5 x 10^4 W.

The car of mass 950kg is moving up a hill at a steady speed.
The slope of the hill is 12° to the horizontal. Resistive forced on the car are negligible.

What is the steady speed of the car? A) 7m/s B) 12m/s C) 34m/s D) 68m/s

This questions seems so simple yet I cannot do it.

*If you need a diagram simply googling the above question should take you to the paper it’s on* Thanks in advance

try using these equations:
Power = driving force x speed
Force = mass x acceleration

if you still stuck then i can give you more help

How did you manage it? I've been stuck on it for about 30 minutes and I can't get the correct answer.
