If the gravitational potential energy of my dassroom projector is 162 J and it is 38 m off the ground, how much
should it weigh?

Fill in the blank. the number of each type of element in the compound (other than 1) is represented by a small number to the right of the element symbol.

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

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.
