3. A smaller 1-kg block is pushed horizontally against a larger 9-kg block by a force F, as shown below. The coefficient of static friction between the two blocks is 0.20, however the ground that the larger block sits on is frictionless. a. Draw a complete free-body diagram for each block. Hint: remember that the blocks exert forces on each other because they are in contact, and do not forget Newton's 3rd law. (10pts) b. What minimum force F is...

A block of mass m = 8.40 kg, moving on a horizontal frictionless surface with a speed 4.20 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.40 kg block recoils with a speed of 0.400 m/s. In the figure, the blocks are in contact for 0.200 s. What is the magnitude of the average force on the 8.40 kg block, while the two blocks are in contact?
