Chapter 3.3, Problem 1bT

For experiment 1,draw and label separate free-body diagrams for glider A and glider M at an instant during the collision (i.e., while the gliders are in contact).

1. While the gliders are in contact, how does the net force on glider A compare to the net force on glider M? Discuss both magnitude and direction.

How, if at all, would this comparison differ if you had chosen a different instant (while the gliders are still in contact)? Explain.

Consider the smell time interval $\left(\Delta t_o\right)$ while the gliders are still in contact. For the two gliders, how does the product ${\stackrel{\to }{F}}_{\text{net,}A}\Delta t_o$ compare to the product ${\stackrel{\to }{F}}_{\text{net,}M}\Delta t_o$ ? Discuss both magnitude and direction. Explain.

Apply Newton’s second law $\left({\stackrel{\to }{F}}_{\text{net}}=m\frac{\Delta \stackrel{\to }{\upsilon }}{\Delta t}\right)$ to each of the colliding gliders in Experiment 1, to compare the change in momentum $\left(\Delta \stackrel{\to }{p}=m\Delta \stackrel{\to }{\upsilon }\right)$ of gliders A and M during the collision. Discuss both magnitude and direction. Explain.
