initial velocity,
b) deceleration.

2. A cheetah can reach a speed of 80 km/h from rest in just 3 seconds.
Change 80 km/h to m/s.
b) Calculate:
i) its acceleration,
ii) the distance it travels,
iii) its average speed.

3. A train moving at 20 m/s increases its speed to 35 m/s while accelerating at 3 m/s2.
Calculate the:
time interval during which it accelerates,
b) distance travelled by the train.
