A basketball referee tosses the ball straight up for the starting tip-off. At what velocity must a basketball player leave the ground to rise 2.05 m above the floor
in an attempt to get the ball? *

6.34 m/s

Explanation:

Given that,

A basketball player leave the ground to rise 2.05 m above the floor  in an attempt to get the ball.

We need to find the velocity must a basketball player leave the ground. Using equation of kinematics as follows :

As it leaves the ground, its final velocity, v = 0

a = -g (opposite to gravity)

or

u = +6.34 m/s

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
