Units and force review Work is equal to force times distance. Remember that Force is equal to mass x acceleration ( kg m/s2 ,Newtons ) and distance must be in meters. The unit for work becomes a joule, so a joule is a Newton meter or Nm.
When using the work equation just multiply the force by the distance it moved and the unit is a joule (J)

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.
