A compressed spring in a toy is used to launch a 8.00-gram ball. If the ball leaves the toy with an initial horizontal speed of 6.00 meters per second, the minimum amount of potential elergy stored in the compressed spring was

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
