Question

A 0.105- kg hockey puck moving at 24 m/s is caught and held by a 75-kg goalie at rest. With what speed does the goalie slide on the ice after catching the puck? Define the puck and the goalie as a system.

please show work, help

Answer 1

0.03 m/s

Step-by-step explanation:

Applying law of conservation of momentum,

• m₁v₁ + m₂v₂ = (m₁ + m₂)v
• 0.105(24) + 75(0) = (0.105 + 75)v
• 75.105v = 2.52
• v = 2.52/75.105
• v = 0.03 m/s
