## Homework Statement

A bike is travel up and over a hill with a radius at the top of the hill of 10 meters. The bike is traveling at 10 m/s at position A and 5 m/s at position. (and the problem comes with a picture showing an angle of 60* between point A and B.

a. Determine the average tangential acceleration while slowing down

b. Determine the centripetal acceleration

c. Determine the net acceleration and its direction

## Homework Equations

I used a(centripetal)=v^2/r and I was unsure of how to get tangential

## The Attempt at a Solution

I evantually came out with a being equal to -2.5 m/s^2 (-5^2/10) and I was unable to get tangential just putting down my best guess which made it impossible for me to get a and c correct
