Ametal block of mass 235 g rests at a point 2.8 m from the center of a horizontal rotating wooden platform. the coefficient of static friction between the block and the platform is 0.437. the platform initially rotates very slowly but the rotation rate is gradually increasing. the acceleration of gravity is 9.8 m/s 2 . at what minimum angular velocity of the platform would the block slide away? answer in units of rad/s.

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
