Astudent of mass m = 78 kg takes a ride in a frictionless loop-the-loop at an amusement park. the radius of the loop-the-loop is r = 20 m. the force due to the seat on the student at the top of the loop-the-loop is fn = 364 n and is vertically down. what is the apparent weight of the student at the bottom of the loop-the-loop?
