Block A sits on top of block B while the two slide down a frictionless ramp and over a circle-shaped hump as shown. Block B has twice the mass of Block A. Consider the situation when the two blocks are at the top of the hump.
A. Draw arrows to indicate the direction of the acceleration vectors for each of the blocks at the instant shown. If either (or both) is zero, state that explicitly,
B. Draw free body diagrams for each of the blocks. Label each arrow using the same scheme as used in the tutorial. Indicate “/ /“ marks, on any third law pairs. Draw your vectors to scale.
C. Is the magnitude of the gravitational force on Block A greater than, less than, or equal to the magnitude of the normal force exerted by Block B on Block A? Explain your reasoning.
D. Is the magnitude of the normal force by Block A on Block B greater than, less than, or equal to the magnitude of the normal force exerted by Block B on Block A? Explain your reasoning.
