4. A 1500 kg car is rolling at 2.0 m/s. You would like to stop the car by firing a 10 kg blob of
sticky clay at it. How fast should you fire the clay?

The clay must be 300 m/s fast in other to stop the car.

For the car to stop, The momentum of the car must be equal to the momentum of the clay.

Formula:

  • MV = mv................. Equation 1

Where:

  • M = mass of the car
  • V = Velocity of the car
  • m = mass of the clay
  • v = velocity of the clay

Make v the subject of the equation.

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

From the question,

Given:

  • M = 1500 kg
  • V = 2 m/s
  • m = 10 kg

Substitute these values into equation 2

  • v = 1500(2)/10
  • v = 300 m/s.

Hence, The clay must be 300 m/s fast in other to stop the car.
