Calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 60 km/h?

Text Solution

Verified by Experts

Initial velocity = 60 km/h
`=(60xx1000 m)/(60xx60s)`
`=(50)/(3)m//s`
Initial K.E. `=(1)/(2) mv^(2)`
`=(1)/(2) xx1500xx((50)/(3))^(2)`
`=20833.3J`
Find kinetic energy `=(1)/(2) mv^(2)=0`
Charge in kinetic energy = charge in kinetic energy
`=2083.3 J`
