As unknown force acts on a 2 kg particle such that it moves in a vertical plane as given in radial-transverse coordinates which are unknown functions of time. At one point of the path, the transverse motion terms are known to be 12345,and the radial position of the particle at the at same point is r=2m/s where ris in meters. Determine the velocity and acceleration(in radial-transverse coordinates )at this position and time
