A 5.0 cm long, 53 grams, thin metal strip is allowed to slide along two parallel rails (that contact it at its ends). A constant 0.76 T magnetic field acts perpendicular to the two rails. If the strip is pulled with a speed of 17.8 m/s an the rails are connected to each other through a 20 omega resistor, then find the induced current in the circuit. Assume that the rod and rails have negligible resistance.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

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.
