A mass (M=2kg) is placed in front of a spring with k=900N/m, compressed d=50cm. The spring is released, shooting the mass forward from A to the spring's equilibrium position at B (A to B is frictionless). The mass then travels along a flat surface from B to C (L=20m), with µk=0.15. At C the surface becomes frictionless and smoothly inclines upwards. The speed of the mass at point D is 0m/s
a) What is the velocity of the mass at B?
b) What is the velocity of the mass at point C?
c) How high is point D above the flat surface?
d) Does the mass make it back to the spring? No credit for simple yes or no answer, must explain why or why not!
