3. [-/5 Points] ASK YOUR TEACHER A mechanic pushes a 2.60 x 10²³-kg car from rest to a speed of v, doing 4,500 3 of work in the process. During this time, the car moves 23.0 m. Neglecting friction between car and road, find v and the horizontal force exerted on the car (a) the speed v m/s DETAILS (b) the horizontal force exerted on the car (Enter the magnitude.) Need Help?
