A weight with a mass of 3 kg is attached to a string of length 50 cm. One end of the string is fixed at the origin (x=0, y =0) and the weight is pushed on a frictionless table top so that it moves horizontally in a circle with constant angular velocity %omega. The weight moves in the x-y plane, z=0. At a certain time the velocity of the mass is vx = -3m/s , vy = 2m/s.(adsbygoogle = window.adsbygoogle || []).push({});

The total force is 54i+24j[N] (Not a given, calculated)

The question is:

At the instant the velocity is as above the string is cut. Where is the mass 4 seconds later? Ignore the effects of gravity and friction.

I really need some help with this one.. Thanks alot
