A car travels 2 km in 80 seconds. How fast was it travelling in meters per second? (Remember 1 km = 1,000 m)
A rocket travels at 1,500 m/s for 20 minutes. How far has it travelled in meters?
(Remember 1 minute = 60 seconds)
The moon is 384,000 km away. How long would it take to get there if you travelled at 100 km/h?
Interpret this distance-time graph.
Interpret this speed-time graph.
A cyclist increases her speed from
2 m/s to 20 m/s in
6 seconds.
What is her acceleration?
A car speeds up from 12 to 36 m/s with an acceleration of
2 m/s2.
How much time did this take?
Many road accidents happen because drivers reaction times are reduced.
Suggest 2 things which can reduce a drivers reaction time.
Stopping distance =
Thinking distance + Braking distance
A car driver sees a red traffic light ahead. She brakes and stops in a total distance of 52 metres. If her thinking distance was 15 metres, what was her braking distance?
Stopping distance =
Thinking distance + Braking distance
A lorry travels 28 m when stopping from a speed of 4 m/s. If his braking distance was 18 m, what was the driver’s reaction time?
