Determine the power required for a 1150kg car to climb a 100-m-long uphill road with a slope of 30° (from horizontal) in 12s (a) at a constant velocity, (b) from rest to a final velocity of 30 m/s, and (c) from 35 m/s to a final velocity of 5 m/s. disregard friction, air drag, and rolling resistance.

part (a) 46958.33 W

part (b) 43125 W

part (c) -57500 W

Explanation:

Given,

part (a)

Given that the velocity is constant,

Total displacement traveled by the car = s = 100 m

Work done by the car to reach at the top of the hill

Hence, power

part (b)

Given,

Total power is equal to the ratio of the change in kinetic energy and total time taken

part (c)

Total power is equal to the ratio of the change in kinetic energy and total time taken
