Question

3) An object has a mass of m=2kg and is moving in uniform circular motion at a radius of r=3.1m.

The object has a tangential velocity of v= 10 m/s.

a. what is the objects centripetal acceleration?

b.what is the object's centripetal force?

Answer 1

a = 32.3 m/s^2

F = 64.6 N

Explanation:

a = v^2 / r

a = 10^2 / 3.1

a = 32.3 m/s^2

F = ma

F = 2 * 32.3

F = 64.6 N
