A mechanic pushes a 2.6 × 10³ kg car from rest to a speed of v, doing 5350 J of work in the process. During this time, the car moves 20.0 m. Neglecting friction between the car and the road, find each of the following.
(a) The speed v (m/s)
(b) The horizontal force exerted on the car (N)
A) (a) 15 m/s, (b) 536 N
B) (a) 10 m/s, (b) 268 N
C) (a) 20 m/s, (b) 267 N
D) (a) 25 m/s, (b) 214 N
