Mt. asama, japan, is an active volcano complex. in 2009, an eruption threw solid volcanic rocks that landed far from the crater. suppose that one such rock was launched at an angle of θ = 58.7 degrees above horizontal, and landed a horizontal distance d = 1200 m from the crater, and a vertical distance h = 780 m below the crater.
write and expression for v0, the initial speed of the rock in terms of θ, d, and h.

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.
