One person drops a ball from the top of a building while another person at the bottom observes its motion. Will these two people agree (a) on the value of the gravitational potential energy of the ball-Earth system? (b) On the change in potential energy? (c) On the kinetic energy of the ball at some point in its motion?
Describe the gravitational potential energy transfers and transformations for a javelin, starting from the point at which an athlete picks up the javelin and ending when the javelin is stuck into the ground after being thrown.
Give an example of something think of as work in everyday circumstances that is not work in the scientific sense. Is energy transferred or changed in form in your example? If so, explain how this without doing work.
The "shot" used in the shot-put event is a metal ball with a mass of 7.3 kg. When thrown in Olympic competition, it is accelerated to a speed of about 14 m/s. As an approximation, let's say that the athlete exerts a constant force on the shot while throwing it and that it moves a distance of 3 m while accelerating. (a) What is the shot's kinetic energy? (b) Compute the force that acts on the shot. (c) It takes about 0.5 s to accelerate the shot. Compute the power required. Convert your answer to horsepower.
(a) A child slides down a water slide at an amusement park from an initial height h. The slide can be considered frictionless because of the water flowing down it. Can the equation for conservation of mechanical energy be used on the child? (b) Is the mass of the child a factor in determining his speed at the bottom of the slide? (c) The child drops straight down rather than following the curved ramp of the slide. In which case will he be traveling faster at ground level? (d) If friction is present, how would the conservation-of-energy equation be modified? (e) Find the maximum speed of the child when the slide is frictionless if the initial height of the slide is 12.0 m.
i) A plane has a take-off speed of 88.3 m/s and requires 1365 m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed. ii) When the speed of an object doubles, does its kinetic energy double? Explain youranswer?
During a long jump Olympic champion Carl Lewis’s center of mass rose 1.2 m from the launch point to the top of the arc. What minimum speed ?i did he need at launch if he was traveling at 6.2 m/s at the top of the arc? (in m/s)
A projectile is fired at an upward angle of 35.0∘from the top of a 145 m cliff with a speed of 165 m/s. Part A What will be its speed when it strikes the ground below? (Use conservation of energy and neglect air resistance.)Express your answer to three significant figures and include the appropriate units.
It's been a great day of new, frictionless snow. Julie starts at the top of the 60° slope with a push-off velocity of 1.7 m/s as shown in the diagram. At the bottom a circular arc carries her through a 90° turn, and then she launches off a 3.0-m-high ramp. How far horizontally is her touchdown point (in m) from the end of the ramp assuming that air resistance is negligible and that the local acceleration due to gravity is 9.80 m/s2?

How much gravitational force does the elephant exert on the mouse? b. How much gravitational force does the mouse exert on the elephant? show all work
Using energy techniques solve the following problem(s)A ball is kicked off of a 60 m tall building with an initial velocity of 12 m/s. What is the magnitude of the velocity of the ball just before it strikes the level ground below? Notice how we don't even need to know the angle of the ball as it left the top of the building to find the magnitude of final velocity. (b) If the ball had left the building with an angle 25° above the horizontal, then at what angle would it strike the ground? (This sounds harder than it is, find the initial velocity in the x-direction. The final velocity in the x-direction will be the same, so calculate the final velocity in the y-direction from the final magnitude of velocity. Now use a touch of trig (an inverse trig function) to find the final angle.)
On a recent trip to Chicago, a plane took off and accelerated to a cruising speed of 640 km/hr at an altitude of 10,000 m above the ground. At cruising speed and altitude, did it have more kinetic or potential energy? A. More kinetic B. More potential C. I cannot tell without knowing the plane’s mass
