A space probe has just performed a flyby close to the planet Jupiter. It is now heading toward the outer reaches of the solar system where it will arrive in orbit around Neptune. Which of the following graphs best represents the relationship between the gravitational force exerted by Jupiter upon the space probe and the space probe's distance from Jupiter?

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.
