1. The problem statement, all variables and given/known data A 3.00 Kg object is moving in a plane, with its x and y coordinates given by x=5t^2-1 and y=3t^3+2, where x and y in meters and t in seconds. Find the magnitude of the net force acting on this object at t=2.00 secs. 2. Relevant equations 3. The attempt at a solution Would you just substitute T in the equations to find the displacement of the object and then sum all the forces? I do not know how to sum the forces after I get the free body diagram drawn. Any tips??
