Final answer:
The acceleration of the bicycler is 3 mph/s.
Step-by-step explanation:
To find the acceleration of a bicycler that goes from 0 mph to 15 mph in 5 seconds, we can use the formula:
Acceleration = (Change in velocity) / Time taken
Now we have to use the given values to find the acceleration.
Change in velocity = Final velocity - Initial velocity = 15 mph - 0 mph = 15 mph
Time taken = 5 seconds
Acceleration = (15 mph) / (5 seconds) = 3 mph/s
Therefore, by using the correct formula the acceleration of the bicycler is 3 mph/s.
