Problem 5.112

At time t1 = 0, particle A weighing 5 oz goes through point P of (x, y, z) coordinates (0, 2, 3) ft with a velocity . At time t2, A goes through a point Q of coordinates (1, 0, 1) ft, and with a velocity .

Determine the angular momentum of A with respect to the origin O at times t1 and t2.

Problem 5.113

At time t1 = 0, particle A weighing 5 oz goes through point P of (x, y, z) coordinates (0, 2, 3) ft with a velocity . At time t2, A goes through a point Q of coordinates (1, 0, 1) ft, and with a velocity .

Determine the time rate of change of the angular momentum of A relative to the origin O at times t1 and t2 if the acceleration of A at times t1 and t2 is  and , respectively.
