A mass of 1.2 kg rotates around an axis with a constant angularacceleration of 1.60 rad/s squared. The displacement radius r of mwith respect to the z-axis is r(t)= x(t)i +y(t)j where x=rcosθ andy= rsinθ. Obtain v=dr/dt and a=dv/dt. Determin the values ofvelocity and acceleration at time t=2s and r=0.3m (θnaught=0rad,Ïnaught=2.00 rad/s)
