The structure has two frictionless pulleys around which a string is wrapped. If W = 44 lb, determine a force system that is equivalent to the forces applied by the string, where this force system consists of a single force, and specify the x coordinate of the point where the force’s line of action intersects the x axis.

it is called kinetic energy

volts times amps 6 x 0.5 3w

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
