Question

How much work (in J) is done to accelerate a car which has a mass of 3700 kg from a speed of 17 m/s to a speed of 30 m/s?

Answer 1

Answer #1

Work done = change in kinetic energy

Work done = (1/2)m(V ² - U ² )

Where V is final velocity, U is the initial velocity

Work done= (1/2)×3700×( 30 ² - 17 ² )

Work done = 1130350 Joules

Or 1.13 × 10⁶ Joules
