Question

A bus of mass 10,000 kg is moving with a velocity
of 60 kmh-1 . Calculate the work done to stop this
bus.

Answer 1

Explanation:

Answer: 1388500 Joules. =1388500 Joules. Hope it helps you!

Answer 2

Answer:

mass of bus = 10000 kg

velocity of bus = 90 km/h = 25 m/s

Work done = Change in kinetic energy

work done= change in K.E.

=1/2mv^2

=1/2(60×10000)

=300000 j

=300 kj
