Question
answer both parts please! 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 0.500-kg ball that is traveling horizontally at 10.0 m/s. Your mass is 79.0 kg If you catch the ball, with what speed do you and the bal move afterward? Express your answer with the appropriate units. If the ball hits you and bounces off your chest, so afterward it is moving horizontally at 8.0 m/s in the opposite direction, what is your speed after the collision? Express your answer with the appropriate units.Explanation / Answer
A) Apply cosnervation of momentum
final momentum = initial momentum
(0.5 + 79)*v = 0.5*10
v = 0.5*10/(0.5 + 79)
= 0.0629 m/s
B) Again Apply cosnervation of momentum
final momentum = initial momentum
0.5*(-8) + 79*v = 0.5*10
v = (0.5*10 + 0.5*8)/79
= 0.114 m/s
