How can gravity be simulated in an orbiting space station?.

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

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

State the following: boyle's law and charle's law
