A small block of mass (m=2kg) is sent from point A with a speed of 7.0 m/s. the indicated heights are h1=6.0 and h2=2.0. considering no friction along the path A-B-C and calculate:
a. the speed of the block at point B
b. the speed of the block at point C
Considering friction along C-D:
c. describe the motion of the object along the CD portion
