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.

Rays of sunlight traveling in the x-y plane reflect off of a glass window which lies in the x-z plane. the sunlight has an incident angle of 30° the reflected light may be partially polarized along which axis?
