An egg is dropped from a third-floor win-
dow and lands on a foam-rubber pad without
The acceleration of gravity is 9.81 m/s2 .
If a 56.3 g egg falls 11.9 m from rest and the
7.29 cm thick foam pad stops it in 6.32 ms,
by how much is the pad compressed? Assume
constant upward acceleration as the egg com-
presses the foam-rubber pad. (Assume that
the potential energy that the egg gains while
the pad is being compressed is negligible.)
Answer in units of m.
I'm not quite sure. I was thinking EP (mgh) = 1/2 kx2, but you aren't given the spring constant.
The Attempt at a Solution
I calculated that just before the egg hit the pad, its velocity was 15.28m/s. After this...I have no clue where to go.
