Units...
Thanks!
Yes my units are correct. I was skimming over my notes from class and I believe we have to use the ∆px=jx=area under the curve equation
to find the ball's momentum:
m(vf)x-m(vi)x but then I don't have "m" this whole thing is equal to jx
and then the area under...
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...
