You stand on a balcony and throw a bouncy ball upwards with 7.2 j of kinetic energy the ball has 8.3 j of gravitational potential energy when it left your hand how much total energy does the ball have as it leaves your hand

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?

Aforce f making an angle with the horizontal is acting on an object resting on the table. which statement is true for the motion of sliding the object on the table?

What’s the kinetic energy of the object? use . erica is competing in the shot put event at a track meet. she hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. the shot’s kinetic energy is joules.
