A spring loaded launcher launches a 10 g ball into the air. The ball reached a maximum height of 1 m above the point where it rests on the compressed spring before launch. The spring constant of the spring in the launcher is 19.6 N/m. What is the distance the spring is compressed? (Work/explanation appreciated. Please don’t just take the points and run.)

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight

In which of the following is positive work done by a person on a suitcase

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
