Question

When a cricket ball is thrown vertically upward it reaches a maximum height of 5 M what was the initial speed of the ball how much time is taken by the ball to reach the highest point

Answer 1

As v2-u2 = 2Gh
And v= 0 ( because velocity is 0 at highest point)
G = - 10m/s2
As v =u + gt
And v =0
U =10m/s
G = - 10m/s

Answer 2

tske v as 0 then h as 5m and g as -10m/s2 then apply v2=u2+2gh then u will be able to10m/s then apply v=u+gt answer will be 1 second
