one more spring question
A block collides with a spring on a horizontal surface
the block compresses the spring x metres from rest position. What was its speed at the instant of collision
Ok so far I know how to do this question
Ee = Ek
.5kx^2 = .5mv^2
but in this question there is a coefficient of kinetic friction between the block and the surface.. not sure how it fits in.
I'm thinking that it is only affecting the Ee part of the equation..so:
Ee = Ek
.5ukx^2 = .5mv^2
is this right?
