A helicopter drops a paratrooper carrying a buzzer that emits a

A helicopter drops a paratrooper carrying a buzzer that emits a 500 Hz signal. A sound receiver on the plane monitors the signal as the paratrooper falls. If the perceived frequency becomes constant at 450 Hz, what is the terminal speed at the paratrooper ? Take the speed sound in air to be 343 m/s and assume the paratrooper always remains below the helicopter.

If a man lifts a 29.0 kg bucket from a well and does 7.00 kJ of work, how deep is the well? Assume that the speed of the bucket remains constant as it is lifted.

A cannonball is fired horizontally from the top of a cliff.

A cannonball is fired horizontally from the top of a cliff. The cannon is at height h = 50.0 m above ground level, and the ball is fired with initial horizontal speed v(initial). Assume acceleration due to gravity to be g = 9.80 . Given that the projectile lands at a distance = 130 from the cliff, as shown in the figure, find the initial speed of the projectile,v(initial)??
