GT Year 10 Speed and acceleration FT

A man runs 300m in 60 seconds. What is his average speed?

• 3m/s

• 6m/s

• 5m/s

• 15m/s

A cyclist travels at 8m/s for 200 seconds.

How far did she travel?

• 160m

• 1600m

• 25m

• 300m

A train travels 6.00 km in 5 minutes. Convert these into metres and seconds, then calculate the train's speed.

• 10m/s

• 15m/s

• 30m/s

• 20m/s

The graph shows a boy's journey to school.

It is the future and he has a jet-pack.

Describe the motion from 0 to 10 seconds

• Constant acceleration

• Stopped

• Constant velocity

• Constant deceleration

Describe the motion from 10 to 24 seconds.

• Stopped

• Constant velocity

• Constant acceleration

• Non-uniform acceleration

How is the motion from 24 to 34 seconds different from the motion from 0 to 10 seconds

• No difference - the boy is stationary in both

• From 24 to 34 seconds is a faster speed

• From 24 to 34 seconds is a slower speed

• From 24 to 34 seconds shows a higher acceleration

Calculate the boy's speed from 0 to 10 seconds.

• 6m/s

• 60m/s

• 600m/s

• 6000m/s

What is the boy's speed from 24 to 34 seconds?

• 25m/s

• 85m/s

• 60m/s

• 10m/s

What is the formula to calculate acceleration?

• Acceleration = change in velocity x time taken

• Acceleration = time taken / change in velocity

• Acceleration = change in velocity / time taken

• Acceleration = change in velocity + time taken

A motorbike accelerates from 10m/s to 20m/s in 5 seconds. What is its acceleration?

• 2.0m/s²

• 4.0m/s²

• 6.0m/s²

• 10.0 m/s²
