A recently patented pile driver pounds piles into the ground by launching 15 kg bowling balls from a spring loaded gun, up around a frictionless loop-de-loop of radius r= 8 m, and down onto the pile. When the spring is compressed by As = 2 m, the bowling balls have a speed of 20 m/s at the top of the loop, as shown. (You may assume g = 10 m/s2.) v = 20 m/s T=8m Find the work done by the frictionless track on a bowling ball as it goes from the gun to the top of the loop. k=? As = 2 m pile

As shown in the figure, a roller-coaster track includes a circular loop of radius R in a vertical plane. A car of mass m is released from rest at a height h above the bottom of the circular section and then moves freely along the track with negligible energy loss due to friction. (a) First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom of the loop.

A simple pendulum is suspended from the ceiling by means of a string of length 2.16 m. Assume that there is no friction or air resistance.

To make a pendulum, a 300 g ball is attached to one end of a string that has a length of 1.4 m and negligible mass. (The other end of the string is fixed.) The ball is pulled to one side until the string makes an angle of 30.0 with the vertical; then (with the string taut) the ball is released from rest. Find (a) the speed of the ball when the string makes an angle of 20.0 with the vertical and (b) the maximum speed of the ball. (c) What is the angle between the string and the vertical when the speed of the ball is one-third its maximum value?

A bead with a hole through it slides on a wire track. The wire is threaded through the hole in the bead, and the bead slides without friction around a loop-the-loop (see figure below). The bead is released from rest at a height h = 3.85R. A (a) What is its speed at point ? (b) How large is the normal force on the bead at point if its mass is 4.85 g? Part 1 of 4 - Conceptualize Since the bead is released above the top of the loop, it starts with enough potential energy to reach point and still have excess kinetic energy. The energy of the bead at point is proportional to h and g. If it is moving relatively slowly, the track will exert an upward force on the bead, but if it is whipping around quickly, the normal force will push it toward the center of the loop. Part 2 of 4 - Categorize The speed at the top of the loop can be found from the conservation of energy for the bead-track-Earth system and the normal force can be found from Newton's second law. Part 3 of 4 - Analyze (a) We define…
