Homework Statement
Just prior to impact with a golf ball (0.042 kg), a clubhead (0.195 kg) is traveling with a velocity of 33.7 m/s horizontally towards the target and a vertical velocity of 0 m/s. The coefficient of restitution between the ball and club is 0.79. Impact lasts for 0.00043 s. The launch angle of the ball after impact is 13.1°. During impact the ball behaves as a linear spring with a stiffness of, K= 1182019, and is maximally compressed from its resting state by Δx = 0.01 m.
What is the velocity of the club, towards the target (in the typical horizontal X direction), immediately after impact?
I'm stuck on this one and I need to know how to do this one in order to do the last four questions on my bonus assignment. Help would be greatly appreciated! Thanks in advance!
Homework Equations
v'={M[V(1+e)-ev]+mv}/M+m
The Attempt at a Solution
v'={0.042[0(1+0.79)-(0.79)(33.7)]+(0.195)(33.7)}/(0.042+0.195)
v'=23.01 (incorrect)
