A 76.0-kg boulder is rolling horizontally at the top of vertical cliff that is 20 m above the surface of a lake, as shown in the figure above. The top of the vertical face of a dam is located 100 m from the foot of the cliff, with the top of the dam level with the surfaceof the water in the lake. A level plain is 25 m below the top of the dam. (a) What must be the minimum speed of the rock just as it leaves the cliff so it will travel to the plain without striking the dam? (b) How far from the foot of the dam does the rock hit the plain?
An archer aims her arrow directly at the stem of a coconut hanging from a nearby palm tree in hopes of knocking it to the ground. At the precise moment she releases the arrow, the coconut loses its life-long battle with gravity and falls from the tree. Why will the arrow still hit the coconut?
