A 1715 kg car accelerates from rest to 21 m/s. What energy E is required to accomplish this? Assume that no dissipative forces act on the car. E = J In terms of to the amount of energy E required to accelerate a car from rest to 21 m/s, how much additional energy ΔE is required to accelerate the car from 21 m/s to twice that speed, 42 m/s ? ΔE = 0 ΔE = 2E ΔE = 3E ΔE = 4E
