Question

5.
4. Draw the distance - time graph when its speed decreases uniformly.(ASR)
What is the average speed of a Cheetah that sprints 100m in 4sec. ? What if it sprints
50m in 2sec? (25 m/s)(AS)​

Answer 1

Answer:

Distance time graph when speed decreases uniformly is given above.

Avg Speed = ∆S/∆t

= (100-50)/(4-2)

=50/2

=25m/s
