Question

A Ball is thrown vertically upward with a velocity of 50m per sec calculate
1. the maximum height to which it rises
2. the total time it take to return to the surface of the Earth.
......Tell me what formula to use .. don't write the complete answer please....!​

Answer 1

Explanation:

1) v^2 = u^2+2 a s

2) S = u t +1/2 a t^2

take 9.8 as a

hope it's helpful to you

Answer 2

Explanation:

maximum height = (u^2)/2g

u= initial velocity, g= accerlation due to gravity

T (total time taken to return or time of flight)

= 2u/g
