You are standing 30 m from a window that is 30 m off the ground. your friend tries to toss you something, but only throws it straight up. if you start from rest and have a maximum acceleration of 2m/s^2, what is the minimum initial velocity that your friend could have thrown the object to enable you to catch it?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
