Your car is broken, so you’re pushing it. If your car has a mass of 868 kg, how much momentum does it have when it’s moving forward at 4.74 m/s (17.1 km/h)?

Momentum = (Mass) x (Velocity)

in the "forward" direction
= 868 * 4.74 = ___ kg m/s

To calculate the momentum of your car, you need to use the formula:

Momentum (p) = mass (m) × velocity (v)

First, let's convert the velocity from km/h to m/s.

Given:
Mass of the car (m) = 868 kg
Velocity (v) = 4.74 m/s

Now, we can substitute the values into the formula:

Momentum (p) = 868 kg × 4.74 m/s

Calculating this multiplication, we get:

Momentum (p) = 4119.12 kg·m/s

So, the momentum of your car when it's moving forward at 4.74 m/s is 4119.12 kg·m/s.
