Question

A ball is the thrown vertically upward with an initial velocity 100 m per sec., simultaneously 2nd ball dropped from a height 200m ,find at what height from the ground and what time the two ball meet​

Answer 1

Answer:

Ball thrown vertically will suffer retardation of 'g'.

time taken by gravity to reduce balls speed to zero.

0=100+(−10)t

t=10sec.

Ball will be at its peak at t=10sec..It will take same amount of time to comeback to ground total time T=
