The cart is 1.8 m/s fast when traveling.

The speed of the cart can be calculated using the formula of momentum.

Momentum:

This can be defined as the product of mass and velocity.

Formula:

  • M = mv.............. Equation 1

Where:

  • M = Momentum of the cart
  • m = mass of the cart
  • v = speed of the cart.

Make v the subject of the equation.

  • v = M/m................... Equation 2

From the question,

Given:

  • M = 0.450 kgm/s
  • m = 250 g = 0.250 kg.

Substitute these values into equation 2

  • v = 0.450/0.250
  • v = 1.8 m/s

Hence, the speed of the cart is 1.8 m/s
