Lorentz transformation (2pt) suppose that an event occurs in inertial frame o with coordinates x- 75 m, y = 18 m, z = 4.0 m at t = 2.0 x 10-5 s. the inertial frame o 'moves in the +x direction with = 0.85c. the origins of o and o' coincided at t = t'= 0. (a) what are the coordinates of the event in o? (b) use the inverse transformation on the results of (a) to obtain the original coordinates

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
