Calculate the centripetal force...

Question

Calculate the centripetal force on a 3.0-kg object moving in a horizontal circular path of 20-m radius with a speed of 8.0 m/s.

Answer 1

Centripetal force is the force that is produced when an object accelerates about a fixed point.

 

 

F_c = mv² / r

 

where:

F_c = centripetal force

m = mass

v = velocity

r = distance about the center of rotation

 

F_c = (3 kg * (8 m/s)²) / 20 m

F_c = 9.60 N
