Question

a ball is thrown vertically upward with a velocity 100 m/s.how much time will it take to reach tha ground?​

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=20sec
