Homework Statement
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?
Homework Equations
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?
