A bicyclist is a person who rides a bicycle.
F = mv^2/r = m x 4.5 x 4.5/8 = 2.531 x mass = 2.531m Newtons; you did not specify the mass
The car is made of steel. the biker is made of flesh, and the bike is pretty much useless in a collision
By going faster the cyclist is storing up kinetic energy which he can spend in rising the hill. If lucky there will be no struggling with the pedals grinding up the hill, and might even coast over it. Without this energy pre-storage, the cyclist would have to provide energy at a rate fast enough to prevent him slowing down too much and falling off and the cyclist might not be capable of this (rate of supply of energy = power).
The calculation depends on the available data. For example, if you have the corresponding information, you can subtract the final speed by the initial speed, then divide the result by the 15 seconds. This will give you the average acceleration for those 15 seconds.
Bicyclist's is the possessive form.
Skinny.

Both a cyclist and bicyclist are a single person who rides or is riding a bike or bicycle which are the same thing. it occurs to me that a cyclist does not need to be going about on two wheels as a bicyclist does by definition.
