Chapter 8, Problem 24A

Calculate the momentum of a 10-kg bowling ball rolling at 2 m/s.

To determine

Themomentum of a bowling ball of given mass moving with a particular velocity.

Answer to Problem 24A

The momentum of the ball is $20\text{kg}-\text{m/s}$

Explanation of Solution

Given:

A bowling ball of mass 10-kg rolling at a speed of 2 m/s.

Formula used:

The momentum of a body represents its inertia while in motion. It can be expressed as the product of mass and velocity of the body ,

  $\text{Momentum}=mv$

Calculation:

Here, speed or velocity of the ball is 2 m/s and its mass is 10-kg. Thus, the momentum is given by,

  $\begin{array}{c}\text{Momentum }=10\times 2\\ =\text{20 kg-m/s }\end{array}$

Conclusion :

The momentum of a bowling ball of given mass moving with a particular velocityis $20\text{kg}-\text{m/s}$ .
