Question

A 15kg cart is rolling at 4 m/s. What is its momentum?

Answer 1

Given:

Mass = 15 kg

Speed = 4 m/s

Let's find the momentum.

To find the momentum, apply the formula:

`\rho=mv`

Where:

m is the mass in kg

v is the velocity in m/s

Hence, we have:

`\begin{gathered} \rho=15*4 \\ \\ =60\text{ kg.m/s} \end{gathered}`

Therefore, the momentum is 60 kg.m/s

ANSWER:

60 kg.m/s
