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.

A small block (2.25kg) travels along a frictionless path at a speed (6m/s) before it reaches a frictionless semi circular path with a radius of 0.5m. 1) at point A, what is the force exerted by the track on the block? 2) the bottom of the track has a length of 15m with friction. Determine the coefficient of kinetic friction between the block and the bottom of the portion of the track if the block just makes it to point B before coming to rest.
A slender bar with a length of 2 ft is pin-connected with a roller positioned on a smooth horizontal surface. The bar is at rest initially, and a horizontal force F is applied to the roller. If F = 13 lb and the weight of the bar is 10 lb, calculate the magnitude of the acceleration of the roller at that instant by neglecting the mass and the size d of the roller. Present your answer in ft/sec² using 3 significant figures. FOR COMARCA 2 ft F

1. (bold type indicates a vector) An object of mass m = 10 kg may rotate in a vertical plane about the fixed point P under the action of gravity. The distance d from the point P to the center of mass C is d = 0.5 m. The moment of inertia Ie about the center of mass C is unknown. The object starts at rest in the position shown and is then released. At the instant of release the acceleration of the center of mass is measured to be a, = (-5 m/sec²)j (i.e., downward). Use the given information to determine the moment of inertià I, about the center of mass. Use g = 10 m/sec?. gravity w go P (f ixed)
