Please, show all of your work. This means show step by step how you arrived at your answer(s). Include any equations or formulas used to arrive at the answer(s). Thanks!
Explanation / Answer
a) since it takes turn, so centripetal acceleration towards centre will be there.
b) deaccelerating so negative acceleration
c) velocity increasing so positive acceleration
d) it is under gravity so in acceleration
e)it is under gravity so in acceleration
f) constant velocity so no acceleration
