Not totally lost but for the most part.. i'm pretty lost.. A Block of mass m = 7.20 kg is released from rest at a heigh of H = 9 m on a curved frictionless ramp. At the foot of the ramp is a spring whose spring constant is k = 306 N/m. What is the maximum compression of the spring, x? Alright so using conservation of energy, i got the final velocity to be 13.2816 m/s. The "ramp" becomes flat, and is frictionless, so there is no acceleration, correct? This is where i am stuck. The only thing i can think of to find the maximum compression of the spring is: F = -Kx Is there anything else i can do? Or is there something i am missing? Thanks.
