Question

A 3250 N car is pushed a distance of 35 m the power was 11375 J, how long did it take?

Answer 1

10.8s

Step-by-step explanation:

Given parameters:

Force on the car = 3250N

Distance = 35m

Power = 11375W

Unknown:

Time taken = ?

Solution:

To solve this problem;

Power is the rate at which work is done

Power =
`(work done )/(time)`

Work done = force x distance = 3250 x 35 = 123200J

Now;

11375 =
`(123200)/(t)`

11375t = 123200

t = 10.8s
