the speed of the roller coaster, in meters per second, is 16.71. At the top of the loop if the radius of curvature is 15 m the downward acceleration of the car is 1.9g. The height of the loop is 14.15 m. If the loop actually starts 6.5 m higher than your answer to the previous part (yet still reaches the top of the loop with the same velocity), how much energy, in joules, did it lose to friction?

A 0.050kg pendulum is hung from the ceiling of a train so that when the train sits motionless on a banked curve which turns to the right with a turn radius of 210m, the pendulum hangs at an angle of 8.0° to the right of a line perpendicular to the ceiling and floor of the train. How fast is the train going around the same curve if the pendulum bob swings 12° to the left of a line running perpendicular to the floor and ceiling?

A toy car with a mass of 0.150kg goes through the top of a loop the loop with a radius of 0.300m while experiencing a downward normal force with a magnitude of 7.35N. What is the speed of the toy car in meters per second as it goes through the top of the loop?
A light, rigid rod is 77.0 cm long. Its top end is pivoted on a frictionless, horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speedat the bottom is required to make the ball go over the top of the circle? Answer : 5.49 m/s

A single bead can slide with negligible friction on a stiff wire that has been bent into a circular loop of radius 15.0 cm as shown in Figure P6.68. The circle is always in a vertical plane and rotates steadily about its vertical diameter with a period of 0.450 s. The position of the bead is described by the angle h that the radial line, from the center of the loop to the bead, makes with the vertical, (a) At what angle up from the bottom of the circle can the bead stay motionless relative to the turning circle?

The figure shows a conical pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.)

What are (a) the tension in the string and (b) the period of the motion?
