Question

John 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. Helifts 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.

1. Which of the following is the most ideally constructed momentum-impulse diagram for the system of croquet ball and mallet together

2. What is the kinematic relationship relating the velocity of the mass center of mallet handle AB v_G and its angular velocity ω?
