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.`

A particle is projected upwards from the roof of a tower 60 m high with velocity 20 m//s. Find (a) the average speed and (b) average velocity of the particle upto an instant when it strikes the ground. Take g= 10 m//s^2
