Question

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 0.400-kg ball that is traveling horizontally at 10.0 m/s. Your mass is 70.0 kg. (a) If you catch the ball, with what speed do you and the ball move after ward

Answer 1

0.38m/s

Step-by-step explanation:

Given data

M1= 0.4kg

U1= 10m/s

M2= 70kg

U2= 0m/s

The system experiences an inelastic collision, the expression for inelastic collision is

M1U1+ M2U1= (M1+M2)V

Subsitute

0.4*10+ 70*0= (0.4+10)*V

4= 10.4V

4=10.4V

V= 4/10.4

V=0.38m/s

Hence the common velocity is 0.38m/s
