Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a

merry-go-round that is rotating with a period of 10 seconds. What is the

centripetal force acting on Tommy?


Sagot :

Answer:

Fc= 47.363 N

Explanation:

First, you need tangential velocity because they don't give that to you in the problem.

So, the formula for tangential velocity is υ=2πr/t.

For this problem its v=2π4/10= 2.513 m/s

Then we plug this into our equation for centripetal force

Fc= 30*(2.513)^2/4=47.363 N

Fc=47.363 N
