Chapter SH, Problem 2.13APP

To determine

To Calculate: The momentum of the mass.

Answer to Problem 2.13APP

  $2,00,000\text{kg}\cdot \text{m/s}$ (south)

Explanation of Solution

Given:

Mass, $m=5000\text{kg}$

Velocity of mass, $v=40\text{m/s}$ (southwards)

Formula Used:

The momentum can be obtained by using the following formula:

  $p=mv$

Here, v is the velocity and mis the mass.

Calculations:

Substitute the values and solve:

  $\begin{array}{l}p=mv\\ p=5000\times 40\\ p=2,00,000\text{kg}\cdot \text{m/s}\end{array}$

Conclusion:

Thus, the momentum of the mass is $2,00,000\text{kg}\cdot \text{m/s}$ in south direction.
