Observer S detects two flashes of light. A big flash occurs at x1 = 1242 m and, 6.06 ?s later, a small flash occurs at x2 = 802 m. As detected by observer S', the two flashes occur at a single coordinate x'.
(a) What is the speed parameter of S', and
(b) what is the time interval between the flashes?
Calculate g for space shuttle territory. A 7.0×10-2-{rm kg} toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with the constant speed of 1.30 m/s in a horizontal circle of radius 0.47 m.
