1. How far does a train travel in the sixth second if it starts from rest with a uniform
acceleration of 4.0 m/s²?
2. A Zambian airways plane leaves Kenneth Kaunda International airport at the same time
(11.00hrs) as an Ethiopian airways plane. Assuming the first plane was moving with a
velocity of 208.33m/s while the second plane was moving with a velocity of 500km/h,
which plane arrives earlier and what is the arrival time difference of the planes assuming
the Zambian airways plane arrives at 12.30hrs.
3. A stone is thrown vertically upwards with a speed of 22m/s. It is caught on its way down
at a point 6.5m above the position it was thrown.
a)
How fast was it going when it was caught?
b)
How long did the trip take?
4. The figure below shows a velocity-time graph for the motion of a race along a race terrain.
