By means of a rope whose mass is negligible, two blocks aresuspended over a pulley.One block wighs 11.0-kg and the other blockweighs 44.0-kg. The pulley can be treated as a uniform solidcylindrical disk. The downward acceleration of the 44.0-kg block isobserved to be exactly one-half the acceleration due to gravity.Noting the tension in the rope is not the same on each side of thepulley, find the mass of the pulley.

Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human hearing) for a period of 9.00 hours
A toddler, initially standing next to his father in the front yard, walks slowly away from his dad in the direction of 30.0? N of E for 3.50 meters. How far was the distance he walked due south
A block has an initial speed V(o) > 0 on a linear trajectory on the surface with friction coefficient u and air resistance (F = cv^2). Derive an equation that will represent the velocity (V) as a function of the position of the block (x). So V(x).
When a person inhales, air moves down the bronchus (windpipe) at 15 cm/s. The average flow speed of the air doubles through a constriction in the bronchus.
