1. An object is attached to a 1 meter string and completes 5 rotation in 1 second. Find the (a) tangential velocity, (b)angular velocity of the object and (c) angular acceleration. 2. An object moving in uniform motion has a centripetal acceleration of 12m/s2. If the radius of the motion is 3cm, what is the frequency of the motion? 3. The angular position of a particle is given by the equation 0(t) = sin 3t + 3t2. Determine the angular velocity and angular acceleration as a function of time. What is the angular position, angular velocity, and angular acceleration of the particle at the start if motion
