What is the centripetal force needed to keep a 3.0kg mass moving in a circle of radius 0.50 m at a speed of 8.0m/s?

384N

Explanation:

Given parameters:

Mass  = 3kg

radius  = 0.5m

Speed  = 8m/s

Unknown:

Centripetal force  = ?

Solution:

The centripetal force is the inward force that keeps a body in motion along a circular path.

It is mathematically expressed as;

      F =  

m is the mass

v is the speed

r is the radius

 Now insert the parameters and solve;

     F  =   = 384N
