You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is
negligible friction between your feet and the ice. A friend throws you a 0.4 kg ball that is traveling
horizontally at 10 m/s. Your mass is 70 kg. If you catch the ball, with what speed do you and the ball
move afterwards?

Two objects, =15.3 kg and =5.31 kg are connected with an ideal string and suspended by a pulley (which rotates with no friction) in the shape of a uniform disk with radius =7.5 cm and mass =14.1 kg. the string causes the pulley to rotate without slipping. if the masses are started from rest and allowed to move 2.5 m:
