Question

Calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 60 kmh-1?

Answer 1

208333 J (approx)

Step-by-step explanation:

Work required to stop = Kinetic energy of car

So,

Kinetic Energy = 1/2 * m * v^2

Convert 60 kmh-1 to ms-1

= 1/2 * 1500 * (50/3)^2

= 208333.33 J
