A mechanic pushes a 2.60 ✕ 103-kg car from rest to a speed of v, doing 4,770 J of work in the process. During this time, the car moves 20.0 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.) N
A mechanic pushes a 3.30 ✕ 103-kg car from rest to a speed of v, doing 4,860 J of work in the process. During this time, the car moves 29.0 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.) N
A mechanic pushes a 2.60 ✕ 103-kg car from rest to a speed of v, doing 4,950 J of work in the process. During this time, the car moves 20.0 m. Neglecting friction between car and road, find v and the horizontal force exerted on the car.
A mechanic pushes a 2.60 times 10^3 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. the speed v m/s the horizontal force exerted on the car (Enter the magnitude.) 193 Your response differs from the correct answer by more than 10 %. Double check your calculations. N
