A train begins a journey from a station and travels 60km in a time of 20 minutes. What is the average speed of the train?

• 3.0 m/s

• 5.0 m/s

• 50 m/s

• 60 m/s

Two runners take part in a race. The graph shows how the speed of each runner changes with time.

What does the graph show about the runners at time t?

• Both runners are moving at the same speed.

• Runner 1 has zero acceleration.

• Runner 1 is overtaking runner.

• Runner 2 is slowing down.

What is the product of speed and time ?

• Density

• Velocity

• Distance

• Displacement

• Moment

• Velocity

• Acceleration

An object is released from rest and falls to Earth. During its fall, the object is affected by air resistance. The air resistance eventually reaches a constant value. Which description about successive stages of the motion of the object is correct?

• decreasing acceleration, then constant deceleration

• decreasing acceleration, then zero acceleration
