The potential difference across the terminals of a battery is 8.40 V when there is a current of 1.50 A in the battery
from the negative to the positive terminal. When the
current is 3.50 A in the reverse direction, the potential
difference becomes 10.20V. (a) What is the internal
resistance of the battery? (b) What is the emf of the
battery?

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.
