Children are playing a game of ice hockey on a frozen lake. One of the children throws a 1200g water bottle with velocity 0.4 m/s to another kid, weighing 41 kg, sitting motionless on the ice who catches the bottle 0.2 m from their COM at angle of impact of 12 degrees. The child on the ice has a center mass moment of inertia of 38 kg m^2. Assuming the ice is perfectly friction-less, answer the following. 1.) How does the catch add to their moment of inertia? 2.) What is the child's rotational motion after he brings the bottle closer to drink so it is now 0.1 m from their center of mass? 3.) How does a greater angle of impact affect the child's rotational motion? 4.) What is the child's rotational motion if the angle of impact was 22 degrees? (please explain using introductory physics techniques, thank you).

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 5.0 m/s, skates by with the puck. After 1.50 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.31 m/s2, determine each of the following. (a) How long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.) (b) How...

A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.450 m/s. The total mass of the sled, man, and rock is 97.5 kg. The mass of the rock is 0.280 kg and the man can throw it with a speed of 17.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in...
