Three boxes in contact slide side-by-side on a smooth, friction-less, horizontal floor. Their masses are 5.0-kg, 3.0-kg, and 2.0-kg, with the 3.0-kg box in the center. A force of 50 N pushes on the 5.0-kg box, which pushes against the other two boxes. A. Draw the free-body diagrams for each of the boxes. B.

Could someone explain for me? Thank you in advance!
Researchers often use force plates to measure the forces that people exert against the floor during movement. A force plate works like a bathroom scale, but it keeps a record of how the reading changes with time. Shown is the data from a force plate as a woman jumps straight up and then lands.a. What was the vertical component of her acceleration during push-off?b. What was the vertical component of her acceleration while in the air?c. What was the vertical component of her acceleration during the landing?d. What was her speed as her feet left the force plate?e. How high did she jump?
Pls help ASAP. Pls give directions and magnitude in each question.

1. A wooden block rests on a wooden table. You push the block to the right; while you are pushing it, you notice the block slows down. Answer the following questions about the block's motion while you are pushing it. a. Draw a force diagram for the block in the space to the right. (For each force that affects the block, draw an arrow showing which way that force pushes the block.) For now, only include the horizontal forces on the block. For each force/push, name the object that is pushing on the block. Also, list the type for each force. b. Is the block in equilibrium? Explain. c. What direction does the velocity of the block point? Explain. d. What direction does the acceleration of the block point? Explain. e. Now add the vertical forces that affect the block to your force diagram above. Are there any other vertical forces on the block besides gravity? How can you tell?
