Question 5 NECO • 2025 • PHYSICS • essay

A 1500 kg car is driven up a straight road that makes an angle of 30\(^\circ\) with the horizontal. The road is rough and the coefficient of rolling friction between the tyres and the road is 0.02. The car moves up the incline at a constant speed, covering a distance of 200 m in 25 s.

Question Parts

( a )

Determine the minimum constant force that the engine must exert to pull the car up the incline at constant speed.

( b )

Using the force found in part (a), calculate the average power output of the engine during the 25 s interval.

( c )

If the engine actually delivers 20% more power than the value obtained in part (b), determine the extra energy that is dissipated as heat during the ascent.
