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.
