This energy transformation diagram represents the energy of a boulder, initially positioned on top of a mountain. As it falls, its original gravitational potential energy is converted to kinetic energy and air friction. How much of the energy is kinetic? J

Examples of states of consciousness include a. daydreaming b. dreaming during sleep c. hypnosis d. all of the above

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
