Homework Statement
A small block is launched on the fricntionless loop the loop shown. te sprink launcher has a sprink constant k
a)find the velocity at the top of the loop as a function of the displacement x of the spring launcher from its equilibrium length
b)find the minimum cvalude of x such that the block goes over the top in contact with the track
c)find the normal force on the bock A as a function of x
Homework Equations
The Attempt at a Solution
I believe i would have to use .5ks2, and then calculate the acceleration, and aply it to uniform circular motion, is this correct
W = .5kx2
K = .5mv2
v = (2W/m).5 = (kx2/m).5
