Finding the mass of a hockey puck - inertia!
An ice hockey puck slides along the ice at 12m/s. A hockey stick delivers an impulse of 4.5 kg * m/s, causing the puck to move off in the opposite direction with the same speed. What is the mass of the puck. Friction and drag are negligible.
Any Ideas? I am completely lost.
Thanks!
