A spring with a spring constant of 1200 N/m has a 55-g ball at its end. The energy of the system is 5.5J. What is the amplitude of vibration?

At the same instant that a 0.50-kg ball is dropped from 25 m above Earth, a second ball, with a. mass of 0.25 kg, is thrown straight upward from Earth's surface with an initial speed of 15 m/s ...

If you throw a ball against the ceiling-so the ball moves upward and then rebounds to move downward-at the instant the ball hits the ceiling, the acceleration is If you throw a ball against the ceiling-so the ball moves upward and then rebounds to

One of your classmates, Kevin, is trying to calculate the acceleration due to gravity at the top of Mt. Everest. Looking at an equation sheet, he sees that the acceleration due to gravity is g = G M r 2. For G, he plugs in the gravitational constant.

A 20-N force applied to the handle of a door produces a 44-N output force. What is the AMA of the handle?

I am looking for this answer : Which shows a correct order of steps in the scientific method? develop a hypothesis, analyze data, make observations, draw conclusions make observations, draw conclusions, develop a hypothesis, analyze data.

A gas in a piston is compressed doing - 439 j of work, and its internal energy increases by 318 j. how much heat flows? (be careful with + and -. + w = expansion. + q = added, + u = temp goes up) (unit = j)

A loop of wire is placed in a uniform magnetic field. (a) For what orientation of the loop is the magnetic flux a maximum? The plane of the loop is perpendicular to the magnetic field. The plane of the loop is parallel to the magnetic field.
