A mechanic pushes a 3.50 ✕ 10^{3}-kg car from rest to a speed of *v*, doing 5,130 J of work in the process. During this time, the car moves 26.0 m. Neglecting friction between car and road, find *v* and the horizontal force exerted on the car.

(a) the speed *v*

m/s =

(b) the horizontal force exerted on the car (Enter the magnitude.)

m/s =

(b) the horizontal force exerted on the car (Enter the magnitude.)

Step 1

a)

The expression for work is

Step 2

Substitute the values in the above expression and solve for v

Step 3

b)

The expression for w...
