Homework Statement
A horizontal spring with k = 71 N/m has one end attached to a wall and the other end free. An 95 g wad of putty is thrown horizontally at 3.7 m/s directly toward the free end.
Find the maximum spring compression.
Homework Equations
W=1/2kx^2
The Attempt at a Solution
Tried squaring the 3.7m/s to get 13.69m^2/s^2 and multiplying that by the weight of the putty to obtain 1.3J, the work done.
Plugging that in...
W=1/2kx^2
1.3J=1/2(71)x^2
x=0.19
which is incorrect.
