The pilot of an airplane executes a loop-the-loop maneuver in a vertical circle. The speed of the airplane is 310 mi/h, at the top of the loop and 450 mi/h at the bottom, and the radius of the circle is 1 480 ft. Note: His apparent weight is equal to the magnitude of the force exerted by the seat on his body.
(a) What is the pilot's apparent weight at the lowest point if his true weight is 160 lb?
(b) What is the magnitude of his apparent weight at the highest point?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
