Question

A basketball referee tosses the ball straight up for the starting tip-off. At what velocity (in m/s) must a basket ball player leave the grownd to rist 1.24 m above the floor in an attempt to get the ball?

Answer 1

Answer:4.93 m/s

Step-by-step explanation:

Given

height to reach is (h )1.24 m

here Let initial velocity is u

using equation of motion

`v^2-u^2=2ah`

here Final Velocity v=0

a=acceleration due to gravity

`0-u^2=2\left ( -g\right )h`

`u=√(2gh)`

`u=√(2* 9.81* 1.24)`

`u=√(24.328)`

u=4.93 m/s
