o 02 points I Previous Answers SerCP105P 009 A mechanic pushes a 2.60 x 10 kg car from rest to a speed of v, doing 5,460 J of work in the process. During this time the car moves 24.0 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.) Your response differs from the correct answer by more than 10%. Double check your calculations. N Need Help? Read

Answer #1

a)

Work done = kinetic energy

5460 = 0.5 m V^2

V = 2.04 m/s

b)

Work done = Fx displacement

5460 = Fx24

F = 227.5 N
