As a test, CJ played croquet with a 0.922-kg. mallet head and you can assume that it can be modelled as a point mass for simplified analysis only in this case. Meanwhile, the mallet's handle has a length of 0.95 m and a mass of 0.63 kg. She lifts the mallet from the ground and swings it down, pivoting around her grasp, to strike the croquet ball. The ball, which is initially at rest, weighs 0.42 kilograms and it has linear velocity of 1.995 meters per second to the right immediately after impact. 0.95 m A 1a. If it is determined that w=1.6 rad/s and TAB=0.0474 kg-m², which of the following best approximates the magnitude of angular velocity, w', of the mallet immediately after impact? A. 0.780 rad/s B. 0.821 rad/s C. 0.402 rad/s D. 0.508 rad/s B 1b. Which of the following best approximates the coefficient of restitution, e, between ball S and the mallet? A. 0.799 B. 0.415 C. 0.508 D. 0.612 As a test, CJ played croquet with a 0.922-kg. mallet head and you can assume that it can be modelled as a point mass for simplified analysis only in this case.
