[SOLVED] spring and box on incline
A 50 kg mass rests atop a 20m high incline. The spring constant of a 10m long spring below is 1000N/m. The 50 kg crate is sent down the incline. Assume all surfaces in this problem are frictionless.
What is the velocity of the crate traveling along the horizontal surface?
V_(f^2 )=V_(i^2 )+2aD
Fspring=kx
F=ma
I am so confused by this problem. I tried to find the length of the incline, but couldn't figure out how. The only thing I could think to do was to find the potential energy of the crate, which is 9810 J. I know that only force gravity is acting of the crate, and that Fgy=FN, but that doesn't seem to help me at all.
Please help me if you can because I have a physics final exam tomorrow. Thank you so much.
