## Homework Statement

Two blocks, of mass M and m, are in contact on a horizontal, frictionless table (w/ the block of mass M on the left and block of mass m on the right). A force F

_{1}, is applied to the block of mass M and the two blocks move together to the right.

a. Draw a FBD

b. Suppose the larger block M exerts a force F

_{2}on the smaller mass m. By N3, the smaller block m exerts a force F

_{2}on the larger block M. Argue whether F

_{1}= F

_{2}or not.

c. Derive an expression for the acceleration of the system.

d. Derive an expression for the magnitude of the force F

_{2}that the larger block exerts on the smaller block.

e. Choose different values of M and m and compare the magnitudes of F

_{1}and F

_{2}

## Homework Equations

## The Attempt at a Solution

a. see attachment

b. acc. to N3, "for every action, there's an equal and opposite reaction force" so F1 = F2 >> the thing is what if M is accelerating?

c. a = F

_{net}/m

d. F

_{2}= ma

...is what I'm doing here...right?
