Dynamic Problem, reply as soon as posible. The double pulley system weighs 30 lbs. and has a 6.5-inch center radius of gyration. Cylinders A and B are connected to the double pulley by cords that wrap around the circles whose radii are shown. The coefficient of kinetic friction between block B and the surface is 0.25. If the system is released from rest at position shown, determine: A) The velocity of cylinder A just before hitting the ground. B) The total distance cylinder B travels before coming to rest.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
