The escape velocity of any object from earth is 11.2 km/s. (a) express this speed in m/s and km/h. (b) at what temperature would oxygen molecules (molecular mass is equal to 32.0 g/mol) have an average velocity v_{rms} rms equal to earth’s escape velocity of 11.1 km/s?

Excuse ! extra points plus ! super desperate ! the position of an object does not move relative to a reference point. relative to the reference point the object _. a.) is not moving. b.) is moving.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

Astone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. the stone rolls down 10 meters and comes to rest on a patch of moss. the gravitational potential energy of the stone on the moss is joules.
