1). A block of a mass 10kg is released from rest at point A.SectionAB of the track is frictionless. Section BD is rough andthecoefficient of kinetic friction between the surface is Uk =0.2. Aspring with a spring constant 600 N/m is fixed to a wall atD.
Find the speed of the block at point B.
Find the block at point C( just before it hits thespring).
How far does the block compress the spring
Determine the maximum hieght to which the block risesafter itleaves the spring.
