Question

What is the acceleration of the motorcycle in section CD?

Answer 1

30m/s²

Step-by-step explanation:

The acceleration of the motorcycle in section CD is the slope of the velocity - time graph.

Given that;

Initial velocity = 20m/s Time = 6s

Final velocity = 50m/s Time = 7s

The time interval = 7s - 6s = 1s

So;

Acceleration =
`(Change in velocity )/(time)` =
`(50 - 20)/(1)` = 30m/s²
