Abasketball player can jump 1.6 m off the hardwood floor. with what upward velocity did he leave the floor? 1.4 m/s 2.8 m/s 4.2 m/s 5.6 m/s

The upward velocity is 5.6 m/s.

(5) is correct option.

Explanation:

Given that,

Height = 1.6 m

We need to calculate the the upward velocity

Using equation of motion

Here, g = acceleration due to gravity

v = final velocity

u = initial velocity

h = height

Put the value into the formula

Hence,  The upward velocity is 5.6 m/s.

the answer is b ) square root of 5
