Answer on Mechanics | Relativity Question for Emmanuel chinonye
2) An astronaut is located in an horizontal centrifuge at a radius of 50m.(a)what is the astronaut speed if the centripetal acceleration has magnitude of 7.0g (b) what is the period of the motion
b) It is 10 m - 3.1 m = 6.9 m
c) The time for 10 m height is t = sqrt(2*h/g) = 1.4 sec and the distance is 20 m/s*1.4 s = 28 m
2) a) The acceleration is a = v^2/R and v = sqrt(aR) = 59 m/s.
b) T = l/v = 2*3.14R/v = 5.3 sec.
