1. A bicyclist moving at a speed of 15.0 m/s rounds a bend with a radius of 28.0 m. What is the centripetal acceleration of the cyclist?

2. A bolt is shot horizontally from a crossbow 1.75 m above the ground. The initial velocity is 40 m/s. How far will the arrow travel before hitting the ground?

3. A tennis ball is thrown toward a vertical wall with a speed of 16.0 m/s at an angle of 37.0 above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 21.0 m.

a. At what height above the point of release does the tennis ball hit the wall?

b. Has the tennis ball already passed the highest point on its trajectory when it hits the wall? Justify your answer.

4. A football is kicked from a tee at 14 m/s at 64 degrees above the horizontal. What is the maximum range of the football?

5. Two people are riding a merry-go-round. One person (rider A) is riding close to the inside edge of the platform (inner part of the donut/circle), and the other (rider B) is riding on the outside edge. The platform is 4.0 m wide, and the whole merry-go-round has a diameter of 12.0 m. The merry-go-round is making one rotation every 60 seconds.

What is the centripetal acceleration that each rider (rider A & rider B) is experiencing?

please please answer all questions it would be GREATLY appreciated. :)))
