A toy launcher uses a spring to launch a small plastic ball.

a.

Just before the ball is released, the spring has a compression of 0.08 m0.08\text{ m}0.08 m.

  • mass of plastic ball = 0.020 kg0.020\text{ kg}0.020 kg
  • spring constant = 200 N/m200\text{ N/m}200 N/m

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

[4]
b.

Complete the sentence:

As the ball climbs upwards through the air, there is a decrease in the ____________ energy of the ball.

[1]
c.

Give one factor that would increase the horizontal distance the ball travels before hitting the ground.
