. In the movies, you sometimes see a scene where a character fires a bullet at victim, who falls backwards from the impact, but the shooter is standing still. Is this realistic? Or movie effect fiction? Explain using the laws of physics. Assuming a 1 gram bullet and that the victim has a mass of 100 kg each, Ignore friction. Does it make a difference if the shooter is on a rug or ice? Explain.

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
