The speed-time graph shows the movement of a car.

What does the shaded area of the graph represent?

• the average acceleration of the car

• the average speed of the car

• the total distance travelled by the car

• the total travelling time of the car

Two men jump out of an aeroplane at the same time. One of the men opens his parachute and

the other man remains in free-fall.

Why is the man in free-fall moving faster than the parachutist?

• The manin free-fall experiences greater air resistance.

• The man in free-fall has a greater mass.

• The parachutist experiences greater air resistance

• The parachutist has not reached terminal velocity

A passenger is sitting in an aeroplane, which takes off and climbs to 10,000m.

What is the mass of the trap door?

• 1.5 kg

• 3.0 kg

• 30 kg

• 150 kg
