The drawing shows a bowling ball suspended from the ceiling of a classroom by a strong cord. The ball is drawn away from itsequilibrium position and released from rest at the tip of a student's nose. The student remains stationary. After one swing when the ballreturns toward the student, will it hit the student's nose?O No, because air resistance will remove some of the ball's kinetic energy, so ball will reach slightly lower.O Yes, because after one swing it returns even higher than it started.O Impossible to determine without knowing the height of the student's nose.

The problem can be understood using the conservation of energy theorem.

Read the text about an object in motion. In a public pool, Samir held an inflatable ball above his head and then pushed the ball down into the water. Samir could feel the ball pushing up against his hands while he held it steady underwater. After a few seconds, he let the ball go. The ball rose to the surface of the water and floated in the pool. When was the least gravitational potential energy stored between the ball and Earth? Assume that the ball's mass did not change. when the ball was above Samir's head when the ball was pushing against Samir's hands underwater when the ball was floating on the surface of the pool

Problem 2: Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes themselves away from the other two across the frictionless ice. After the push, Skater A with mass 80 kg moves in the negative y-direction at 3.5 m/s and skater B with mass 75 kg moves in the negative x-direction at 4 m/s. Find the x- and y-components of the 90 kg Skater C's velocity after the push. Assume a birds-eye view of the situation for your coordinates.

A physics teacher had a bowling ball suspended from a very long rope attached to the high ceiling of a large lecture hall. To illustrate his faith in conservation of energy, he would back up to one side of the stage, pull the ball far to one side until the taut rope brought it just to the end of his nose, and then release it. The massive ball would swing in a mighty arc across the stage and then return to stop momentarily just in front of the nose of the stationary, unflinching teacher. However, one day after the demonstration he looked up just in time to see a student at the other side of the stage push the ball away from his nose as he tried to duplicate the demonstration. Tell the rest of the story, and explain the reason for the potentially tragic outcome.
A bowler tosses a ball without spin. The ball slides down the alley. At some point, friction with the alley makes the ball start to roll; eventually, it rolls without sliding. When the ball reaches this point, it is moving at a lower speed than the original toss. Use energy concepts to give two reasons for this change.

1. So imagine a wombat named Horace at rest. It's somehow on the top of a long telephone pole. It has a mass of 44.0 kg. It then slides down the pole reaching a final speed of 5.95 m/s just before reaching the bottom 12.4 later. (a) Calculate the change in the gravitational potential energy of Horace from top to bottom. (b) What is Horace's kinetic energy just before reaching the bottom? (c) What is the average force of friction that acts on Horace while sliding?

A basketball is rolling down a hill. When you start watching it, it has a total energy of -11 Joules. When it reaches the bottom of the hill, it has a vertical position of -6 meters. If the basketball weighs 0.6 kg, what is the kinetic energy in units of Joules of the basketball when it reaches the bottom of the hill? Assume the system is closed and the effects of friction are negligible. Recall that g = 10m
The bicep curl is an exercise where you lift up a barbell with weights attached by bending your arms at the elbow. Assume your forearm length (elbow to hand) is 0.516 m, and the barbell is lifted a vertical distance that is twice the forearm length. Also assume that the barbell is at rest at both the start and the end of the motion. Calculate how much energy it takes to curl a barbell with a total weight of 72.8 lb? Image size: s ML Max
