Homework Statement
A 4.29-kg ball of clay is thrown downward from a height of 2.53 m with a speed of 4.21 m/s onto a spring with k = 1770 N/m. The clay compresses the spring a certain maximum amount before momentarily stopping.
a) Find the maximum compression of the spring.
b) Find the total work done on the clay during the spring's compression.
Homework Equations
Ep = mgh
Ek = 1/2mv2
Espring = 1/2kx2 (k: spring constant, x: compression length)
The Attempt at a Solution
I tried two equations but I couldn't find the true answer.
First equation I solved is
mgh + 1/2mv2 = 1/2kx2
And the second one is
mg(h+x) + 1/2mv2 = 1/2kx2
