Question

10.

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?

1.02 m/s

0.06 m/s

0.02 m/s

0.12 m/s

Answer 1

Step-by-step explanation:

This is a classic Law of Momentum Conservation problem. For us the equation will look like this:

`[(m_yv_y+m_bv_b)]_b=[(m_y+m_b)v_(both)]_a` Filling in with our given info:

`[(70.0)(0)+(.40)(10.0)]_b=[(70.0+.40)v_(both)]_a` and

4.0 = 70.4v and

v = .06 m/s
