Question

A 2 kg basketball is thrown towards a stationary 1.35 kg kickball with a velocity of 2.37 m/s. After impact the kickball moves forward at a rate of 1.5 m/s. What is the velocity of the basketball after the collision?

Answer 1

Given,

Mass of basketball is 2 kg.

Mass of kickball is 1.32 kg

The initial velocity of the basket ball is 2.37m/s.

The final velocity of the kickball is 1.5 m/s

By conservation of momentum,

$\begin{gathered} 2\times2.37=1.32\times1.5+2v \\ \Rightarrow v=\frac{1.38m}{s} \end{gathered}$

The velocity of the basketball is 1.38 m/s
