The total mass of the skateboarder and skateboard is 50 kg.

Gravitational field strength (ggg) = 10 N/kg

a.

Calculate the decrease in gravitational potential energy of the skateboarder and skateboard from A to B.

[2]
b.

The speed of the skateboarder at B is 5.0 m/s.

Calculate the kinetic energy of the skateboarder and skateboard at B.

[2]
c.

Calculate the energy dissipated as the skateboarder moves from A to B.

[2]
d.

Explain how the energy is dissipated.

[2]
e.

The skateboarder does not push off with her feet at any time.

Explain why she cannot reach the top of the right-hand side of the ramp.
