A pinball machine uses a spring-loaded plunger to launch a heavy steel ball bearing.

Pinball Plunger Diagram

a.

Just before the ball bearing is released, the spring has a compression of 0.05 m0.05\text{ m}0.05 m.

  • mass of steel ball bearing = 0.040 kg0.040\text{ kg}0.040 kg
  • spring constant = 400 N/m400\text{ N/m}400 N/m

Calculate the maximum speed of the ball bearing just after it is released. Give the unit.

[4]
b.

Complete the sentence:

As the ball bearing travels up a steep ramp inside the machine, there is a decrease in the ____________ energy of the ball bearing.

[1]
c.

Give one factor that would increase the horizontal distance the ball bearing travels if it is launched off the end of the ramp into the air.
