Question

A laboratory cart with a mass of 7 kilograms moves a distance of 0.5 meters in 3 seconds.Calculate the momentum.

Answer 1

Given that the mass of the cart is m = 7 kg.

The distance is d = 0.5 m.

The time is t = 3 s.

We need to find the momentum, p.

The formula to calculate momentum is

`\begin{gathered} p=mass* velocity \\ =m*(d)/(t) \end{gathered}`

Substituting the values, the momentum will be

`\begin{gathered} p=7*(0.5)/(3) \\ =1.167kg\text{ m/s} \end{gathered}`

Thus, the momentum is 1.167 kg m/s.
