1. The problem statement, all variables and given/known data A box of mass m = 40kg is released from rest at thte top of a frictionless ramp. The ramp makes an angle theta = 45 degrees to the horizontal. After sliding fom the rigin a distance d = 2.00 m down the ramp, the box strikes a spring of force constant k = 500 N/m. The box compresses the spring momentarily stops, and then begins to slide back up the ramp. What is the maximum speed of the box? 2. Relevant equations 3. The attempt at a solution mgsin(45) = kx (9.81 * 40)sin45 = 500x x= 0.5547 1/2(k)(x^2) = 1/2(m)(v^2) v = 1.96m/s Can anyone verify this pls?
