Answer 1

Answer on Question #48881-Physics-Mechanics | Kinematics | Dynamics

A man of $2\mathrm{kg}$ is thrown in the direction east with $2\mathrm{m/s}$ velocity what is it's momentum?

Solution

The momentum is

$$\vec{p} = m \vec{v},$$

where $m$ is the mass and $\vec{v}$ is velocity.

So,

$$p = m v = 2 \mathrm{kg} \cdot 2 \frac{\mathrm{m}}{\mathrm{s}} = 4 \frac{\mathrm{kgm}}{\mathrm{s}}.$$

Answer: $4 \frac{\mathrm{kgm}}{\mathrm{s}}$ in the direction east.
