Asingle stage axial compressor has a rotor velocity, u = 314 m/s, at the mean radius of 1 meter. the axial flow velocity remains constant through the stage at a value of 100 m/s. 1 = 0 degrees and 2 = 30 degrees. cp = 1 kj/kgk,  = 1.4 and r= 287 j/kgk. a) draw the velocity triangles (superimposed on each other) for the inlet and outlet of the rotor. b) what are 1 and the magnitudes of c1 and w1? c) what is c?

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?

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.
