A bicyclist starts at rest at the top of a 503m long hill

Question

Provide me the accurate solution of the following problem

Problem- A bicyclist starts at rest at the top of a 50.3m long hill. After a small push, he coasts speeding up with an acceleration of 3.43m/s² due to the slope of the hill. At the bottom of the hill, the cyclist coasts to a stop in a distance of 190m. The tires on the bicycle have a radius of 0.550m.

Part 1- What is the angular velocity of the bicycle tires at the bottom of the hill?

Part 2- What is the angular deceleration that the tires experience while coasting to a stop?

I need experts help to drive the answer of the above problem.
