Question 6
F

A car of mass 1200 kg is travelling at 12 m/s.

a.

Calculate the energy in the kinetic energy store of the car.

[3]
b.

The driver doubles the speed of the car to 24 m/s. Explain why the energy in the kinetic energy store of the car becomes four times larger.

[2]
c.

A second car has the same kinetic energy as the 1200 kg car travelling at 12 m/s, but the second car has half the mass. Give the effect of the smaller mass on the speed of the second car.
