A bicyclist accelerates at 0.89 m/s2 during a 5.0 s interval. What is the change in the speed of the bicyclist and the bicycle?

Answer: 4.45 m/s

Explanation:

Given that

bicyclist acceleration = 0.89 m/s2

Time taken = 5.0 seconds

change in the speed = ?

Recall that acceleration is the rate of change of velocity or speed per unit time. So, Acceleration = change in speed / Time

Change in speed = Acceleration x Time

= 0.89m/s2 x 5.0 seconds

= 4.45 m/s

Thus, the change in the speed of the bicyclist and the bicycle is 4.45 m/s
