in Monkey and hunter case . my doctor want me to write a 5 lines about what I have learned from this screenshot. ( The simulation shows the classic physics situation of a monkey and hunter. In this case, the hunter is trying to tranquilize the monkey, so the monkey can be relocated to a better habitat. The monkey is clever—when the tranquilizer dart (in blue) leaves the gun, the monkey (in purple) lets go of the tree branch, and starts to fall straight down. Note that there is a net (not shown) at the bottom to catch the monkey, so the monkey won't get hurt.)

15. The following plot shows the speed v(r) at which stars orbit about the center of a galaxy, as a function of their distance r from the center. v(r) Assuming the galaxy has a spherically symmetric mass distribution, which plot best shows the mass of the galaxy M(r) enclosed within radius r?
