A mechanic pushes a(n) 2960 kg car from
rest to a speed of v, doing 5023 J of work in
the process. During this time, the car moves
20.9 m. Neglect friction between car and road.
Find the speed v

Then, find the horizontal force exerted on the car.

Question

A mechanic pushes a(n) 2960 kg car from
rest to a speed of v, doing 5023 J of work in
the process. During this time, the car moves
20.9 m. Neglect friction between car and road.
Find the speed v

Then, find the horizontal force exerted on the car.

anonymous · Answer

5023 = 0.5(2960)v^2

v = [(5023)/(0.5)(2960)] ^(0.5)

anonymous · Answer

The horizontal force = 5023 / 20.9
