Let a ball is thrown vertically upwards with speed u m/s . at maximum height velocity of ball becomes zero.
so, final velocity of ball , v = 0
time taken to reach the maximum height , t = 10s
acceleration due to gravity , g = 10m/s² [downward ]
using formula, v = u + at
0 = u + (-g)t
or, u = gt
= 10m/s² × 10s
= 100 m/s
hence, Initial velocity of ball is 100m/s
