An object of mass m starts from rest and slides a distance d down a frictionless incline of angle @?

Question

while sliding it contacts an unstressed spring of negligible mass . The object slides an additional distance x as it is brought momentarily to rest by compression of spring .....FIND THE INITIAL SEPARATION D BETWEEN OBJECT AND SPRING ...............THANKS FOR UR HELP!!

Answer 1

D = (Vf)^2 / (2gsin(@)) + (mgsin(@))/ k

Where Vf = final velocity of block when it touches spring
g = gravity
@ = angle above horizontal
k = spring constant
