However the

TOTAL DISTANCE = AVERAGE SPEED x TIME

If you are in car that changes its speed

The same also applies to the velocity. You can work out the average velocity of something in just the same way.

If you are in car that changes its velocity

Work out the average velocities of some members of your class:

(a) on their way to school

(b) during a Physics lesson

PROBLEMS

1. If the changes in speed are steady work out the average velocities for:

(a) a car going from 30m/s to 50m/s

(b) a cyclist going from 10m/s to 4/s

(c) a train going from 0m/s to 50m/s

(d) a bus going from 12m/s to 9m/s

2. Work out the distances travelled by the vehicles in question one if they change their speed in :

(a) 15s (b) 3 mins (c) 20 mins (d) one hour
