Homework Statement



A small body of mass 0.51 kg is attached by a 0.52 m long cord to a pin set into the surface of a frictionless table top. The body moves in a circle on the horizontal surface with a speed of 2.1π m/s.
(a) What is the magnitude of the radial acceleration of the body?
m/s2

(b) What is the tension in the cord?

radial acceleratio is same as centripetal accelaration.

aR=v2/r=w2r=wv

Good luck!!
