A bicycle starts at 2.5m/s and accelerates along a straight path to a speed of 12.5m/s in a time of 4.5 seconds. What is the bicyclist’s acceleration to the nearest tenth of a m/s^2 ?

The bicyclist's acceleration is 2.2m/s^2

Explanation:

Given

---- Initial Velocity

---- Final Velocity

---- Time

Required

Determine the acceleration

This will be solved using the first equation of motion

Substitute values for v, u and a

Collect Like Terms

Solve for a

---- (approximated)

Hence, the bicyclist's acceleration is 2.2m/s^2

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
