If a masss of 65kg is dropped 4.3m onto a spring with a stiffness coefficient of 6.2x10^4 n/m, how far is the spring depressed?

M g (H +x) = (1/2)kx^2

Solve for x.

H = 4.3 m

k is the spring constant

M is the mass

You're welcome.

They may want you to solve it without the x on the left side. That will give you nearly the same answer, and make solving easier, but it will be wrong. Gravity continues to act as the spring is compressed.

how much force is required to accelerate an 8.00 kg mass at 15.00 m/s2?
