(b) how far has he traveled in this time? (c) what is his speed when he catches up?

a.

b.

c.

Explanation:

The bicyclist's friend moves with constant speed. So, we have:

Th bicyclist moves with constant acceleration and starts at rest (). So, we have:

a. When he catches his friend, both travels the same distance, thus:

b. We can use any of the distance equations, since both travels the same distance:

c. The bicyclist final speed is:

what is the question because that is not a question.

the maxium height is 34m/s
