Textbook Question
Chapter 2.1, Problem 1eT
Consider the following discussion between two students.
Student 1: “I think the free-body diagram for the block should have a force by Chris, a force by the rope, and a force by Pam.”
Student 2: “I don’t’ think the diagram should show a force by Pam. People can’t exert forces on blocks without touching them.”
With which student, if either, do you agree? Explain your reasoning.

Assume the ramp in the figure below is frictionless. If the blocks are released from rest, does the 10 kg block slide up the ramp or down the ramp? What is the magnitude of its acceleration? (Remember that you do not need to use the same coordinate system for both free-body diagrams.)
From Figure 101, what is the free-body diagram at the point where the greatest number of forces are concentrated?
The figure below are the two free body diagrams. Write x and y components of
the net force for each diagram. (in the form as: Fnet,x = F1Sin1 – F2Cos2, F1 and
F2 are the magnitude of vector and )

The boy has a velocity of v = 0.38 m/s to the left. What would be the girl's velocity in this case? (Consider the ice to be frictionless. Enter the magnitude only.) Two ice skaters, a boy on the left and a girl on the right, face each other in figures a and b, which depict, respectively, before and after pushing off from each other. Before: The two ice skaters face each other with the palms of their hands facing towards each other and touching the other person's palms. After: The two ice skaters have pushed off and now have their arms outstretched facing each other. A left-pointing arrow above the left skater is labeled "v". A right-pointing arrow above the right skater is labeled "?".arrow_forwardA contestant in a winter sporting event pulls an m kg block of ice across a frozen lake by applying a force F at an angle θ above the horizontal as shown.
