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 e (?) = ??? ?? + ???. 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? 4. Calculate the centripetal acceleration for an object on the surface of radius 4000 km and, and the day is equal to 120 000 seconds. 5. A particle is moving along a circular path of radius 1.5 m and has an angular velocity of 10 rads/s. What is the particle's radial acceleration? What is the particle's tangential velocity? 6. An object sweeps out a central angle of 1/2 radians in 0.50. seconds as it moves along a circle of radius 2 m. Find its linear and angular speed over that time period. 7. An object travels a distance of 30 ft in 3 seconds as it moves along a path of radius 3ft. calculate for the linear and angular speed over the time period
