a mass of 100kg moves in a circular path of radius of 5cm with uniform speed of 20m/s.find the centripetal acceleration and centripetal force.

2 answers

horizontal path?

acceleration=v^2/r=20^2/.05

force= mass*acceleration
But you have a typo I suspect. No way 100 kg is moving at any such speed at five cm. Maybe 5 m or 1 kg or something.
