Chapter SH, Problem 2.12APP

To determine

To Calculate: The momentum of the car.

Answer to Problem 2.12APP

  $36000\text{kg}\cdot \text{m/s}$ (west)

Explanation of Solution

Given:

Mass of car, $m=1200\text{kg}$

Velocity of car, $v=30\text{m/s}$ (westwards)

Formula Used:

The momentum of the car can be obtained by using the following formula:

  $p=mv$

Here, v is the velocity and m is the mass.

Calculations:

Substitute the values and solve:

  $\begin{array}{l}p=mv\\ p=1200\times 30\\ p=36000\text{kg}\cdot \text{m/s}\end{array}$

Conclusion:

Thus, the momentum of the car is $36000\text{kg}\cdot \text{m/s}$ in west direction.
