A stone is thrown onto the roof of a building of heighth with an initial
speed of (42 mshot an angle of projection of 60°. The stone
landed on the roof at point. A 6.0 seconds after the throw
Calculate
a) The maximum height reached by the stone .
b) The height h of the building
c) The velocity of the stone just before hitting the roof of the
building

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?
