2. A train undergoing uniformly accelerated motion changed its velocity from rest to a velocity of 36m/s in 12 sec. Calculate:
A. The acceleration of the train
B. The time to attain a velocity of 24m/s
C. The velocity after 10 sec.
D. The average velocity after 6Sec.
E. The distance covered after 8 sec.
F. The time required to cover 27m
G. The distance where its velocity is 16 m/s

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?
