13. (50 points) A spring with a spring constant of 3000 N/m is compressed 20 cm to launch a 300-g block along the path shown in the figure below. Assume the surface is frictionless until the 45° incline. h2 = 15 m h = 10 m 45° (a) What is the block's speed immediately after losing contact with the spring? (b) What is the the block's speed just before moving up the 45° incline? Assume the block remains in contact with the surface at all points. (c) The coefficient of kinetic friction on the 45° incline is 0.20. What is the block's speed at the top of the ramp? (d) What is the change in kinetic energy of the block between the top and bottom of the ramp? Where did the energy go? (e) What horizontal distance d does the block travel through the air? State any assumptions.
