Question

a volleyball is hit upward with an initial velocity of 7.5 m/s. calculate the displacement of the volleyball when its final velocity is 2.2m/s upwad

Answer 1

The displacement of the volleyball is 2.62 m

Step-by-step explanation:

Given;

initial velocity of the volleyball, u = 7.5 m/s

final velocity of the volleyball, v = 2.2 m/s

displacement of the volleyball, d = ?

Apply the following kinematic equation;

v² = u² - 2gd

2gd = u² - v²

`d = (u^(2)-v^(2) )/(2g)\\\\d = (7.5^(2)-2.2^(2) )/(2*9.8)\\\\d = 2.62 \ m`

Therefore, the displacement of the volleyball is 2.62 m
