11. The velocity of a particle is v)-(-2t) i+ (6t+2)jm/s What is the magnitude and direction of the acceleration of the particle at t 3 s?
6. A ball is tied to the end of a cable of negligible mass. The ball is spun in a circle with a radius 2.00 m making 7.00 revolutions every 10.0 seconds. What are the (a) magnitude of the angular velocity in rad/s, (b) linear velocity in m/s, and (c) centripetal acceleration of the ball (in m/s')? Hint: 7 revolution divided by 10 seconds gives 0.7 rev/s, convert to rad/s
