I see, how would one go about calculating the energy?
If a 135lb man were to throw himself at the pendulum, and pretending that the man transferred all his kinetic energy into the bag, how would it be calculated?
Hello,
In an attempt to end a very long and cringe-worthy debate I would like to ask this question.
How could one calculate how much force is required to move a 300lb pendulum(a heavy punch bag) to an angle of 90 degrees?
I have vague notions of how it could be done, but I certainly couldn't...
