Arod of mass m = 116 g and length l = 49 cm can rotate about a hinge at its left end and is initially at rest. a putty ball of mass m = 14 g, moving with speed v= 6 m/s, strikes the rod at angle a = 37º a distance d=l/4 from the end and sticks to the rod after the collision.
(a) what is the total moment of inertia, 1, with respect to the hinge, of the rod-ball-system after the collision?
(b) enter an expression for the angular speed w of the system immediately after the collision, in terms of m, v, d, 0,
(c) calculate the rotational kinetic energy, in joules, of the system after the collision

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.
