Question 39
F

A ball of mass 0.15 kg is thrown vertically upwards. It leaves the hand at a speed of 8.0 m/s.

Gravitational field strength (ggg) = 10 N/kg

a.

Calculate the kinetic energy of the ball as it leaves the hand.

[2]
b.

Describe the changes in the way energy is stored as the ball rises to its highest point.

[2]
c.

Air resistance can be ignored.

Calculate the maximum height the ball rises above the hand.

[3]
d.

In practice, air resistance acts on the ball.

Explain why the ball does not reach the height calculated in (c).
