block of mass m=2.6kg is placed on an inclined plane that makes an angle of 30 degrees
with the horizontal. It is given an initial speed UP the ramp and slides a distance 1.4m up
the ramp before a complete stop. The coefficient of kinetic friction is between the ramp
and the block is 0.25. Hint: draw a picture of the problem
(a) Draw the forces on the picture and list all the forces acting on the block
(b) Calculate the magnitude and specify the direction of each the forces (be clear about your
choice of coordinate system)
(c) What is the magnitude of the work done by each of the forces
(d) What is the magnitude of the initial velocity of the block?
