Ok, I believe this is a solvable problem, relating to pedulum, collision, and conservation of energy problems. This is what I have so far:
Length of putter=.9144m (Do you think this measurement is sufficient or do I need to measure all the way to between the golfers shoulders?)
Mass of putter head=.45kg (Do you think I’d need to know the mass of the arms of the golfer and putter shaft too?
Height (h) putter raised for 20 deg. backswing= L-Lcos20 =.0551m
gravity= 9.8 m/s^2
PE=h*g*m
Velocity: PE + KE (top of backswing) = PE’ + KE’ (bottom or vertical part of the swing where impacts golf ball)
(.0551)(9.8m/s^2)(.45kg) + 0 = 0 + 1/2(.45kg)v^2
v = 1.04m/s
Impulse time between putter and golf ball= .005s
At this point, I can’t figure out how to derive the amount of force the putter (swinging at 1.04m/s) will transfer to the golf ball (after impulse of .005s).
I believe I’d have to do something with the kinetic energy of the putter, impulse time, & F=m*a
Thnx
