4. Oscar the Grouch drops Slimey into a mine shaft 200m deep. If the temperature is 15.0C, how much time will elapse between the moment when the stone is released and the moment when the sound of the stone hitting the bottom of the mine shaft is heard?

a 245-kg boulder is dropped into a mine shaft thats is 3.0x10^3 m deep. During the boulder's fall, the system consisting of the earth and boulder loses a certain amount of gravitational potential energy. it would take an equal amount of energy to "free" the boulkder from the shaft by raising it back up to the top, so this can be considered the system's binding energy (a) determine the binding energy in joules of the system and (b) how much mass does the system lose when the boulder falls to the bottom of the shaft?

A boy stands on a diving board and tosses a stone into the swimming pool. The stone is thrown from a height of 2.50 m above the water surface with a velocity of 4.00 m/s at an angle of 60.0o above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in water. After the stone enters the water, it moves in a straight line in the direction of the velocity it had when it struck the water. If the pool is 3.00 m deep, how much time elapses between when the stone is thrown and when it strikes the bottom of the pool?

A child throws a stone with a speed of 15m/s at an angle of 60degrees above the horizontal. The stone follows the usual parabolictrajectory and falls into a well. The sound of the stone hittingthe water is heard 2.96 seconds after the child threw it.

A) How far below the ground is the water level in the well?
B) Determine the horizontal distance between the child and thewell.

Make the following assumptions: 1) The stone leaves the hand ofthe child at ground level. 2) The sound of the splash movesvertically up the well and then horizontally toward the child. 3)The width of the well is negligible. 4) Air resistance isnegligible.
