Find the average velocity of a particle ...

Find the average velocity of a particle released from rest from a height of `125 m` over a time interval till it strikes the ground. Take `g=10 m//s^2.`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`t=sqrt(2h)/g = (sqrt(2xx125)/10)=5s`
`v_(av) =s/t=125/5=25 m//s` (downward)
