A wooden block of mass 3m lies on the horizontal section of a frictionless track. The track continues to the right with a circular loop of radius R. A small bullet of mass m is fired from a gun with an initial velocity vo. The bullet strikes the block and remains embedded in the block as it moves around the circular section. a. Find the minimum velocity of the bullet that enables the block to rise to
b. Find the minimum velocity of the bullet that enables the block to
c. Find the normal force on the block from the ramp when it returns to the the top of the loop. complete the loop lowest point of the loop.
