Question
A moving 4.6 kg block collides with a horizontal spring whose spring constant is 366 N/m. The block compresses the spring a maximum distance of "d" m from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is 0.18. If the work done by friction force is -785 mJ:
A) What is the maximum distance "d" ? (Remember that the friction force depends only of FN)
B) What is the work done by the spring on stoping the block ?
C) What is the speed of the block when it hits the spring?
Explanation / Answer
0.5*m*v*v = 0.5*k*x*x
m =mass
v=velocity
k=spring constant
x= compression in spring
no data so i explained clearly formula just use data and u will get answer what u need
