Acyclist going downhill is accelerating at 1.2 m/s2. if the final velocity of the cyclist is 16 m/s after 10 seconds, what is the cyclist’s initial velocity? a. 4 m/s b. 12 m/s c. 18 m/s d. 20 m/s

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

The answer is frictional force

You can find results and justify them? you can test your hypothesis
