Awatermelon is blown into three pieces by a large firecracker. two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction. both of these pieces fly away with a speed of v = 31 m/s. the third piece has three times the mass of the other two pieces.

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.
