Question:

Hockey Swing - Physics help?

by  |  earlier

I need to work out the power (i think) or kinetic energy that is produced by a hockey swing. i dint know if that is possible but i need some way of comparing the swing to the kinetic energy of the ball to work out how much energy or power(whatever) is lost.

If anyone can help that would be awesome!

  1. Vague problem but in a typical collision problem, you determine the initial velocity of the moving object (stick head) right before the collision with the stationary puck.  During the collision, energy is lost but momentum is conserved. I assume that the post-collision velocity of the stick head becomes zero so m1v1 = m2v2. This allows you to find the initial post-collision velocity of the moving puck.  Knowing the puck mass allows you to find the kinetic energy of the puck.
