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
