Consider a 3 kg object moving in a 2.5 m radius circle at 5.7 m/s to answer the next 2 questions.
4. How much force is required to keep the object moving in the circle?
5. What is the acceleration of the object?
For the first one:
a=(v^2)/r = (5.7^2)/2.5 = 12.9996
thus, F=3*12.9996 = 38.988N
The Attempt at a Solution
I think I got the first one. Is that one the right answer? I can't figure out the second one though. Thanks for your help!
