A block of mass m = 3.20kg slides from rest a distance d down a frictionless incline at angle θ = 30.0° where it runs into a spring of spring constant 425 N/m. When the block momentarily stops, it has compressed the spring by 22.0 cm.
(a) What is the distance d?
I found this to be 0.436 meters.
(b) What is the distance between the point of first contact and the point where the block's speed is greatest?
I cannot figure this one out. I thought it would just be zero, but that answer isn't correct.. A block of mass m = 3.20kg slides from rest a distance d down a frictionless incline at angle θ =
