A lead ball is dropped into a lake from a diving board 6.10 m above the water. After entering the water, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 3.10 s after it is released. How deep is the lake? Express your answer with the appropriate units.

At a lab investigating fire extinguisher foams, a heavy ball is accidentally dropped into a deep vat of foam from a crane 5.10 m above the foam. After entering the foam, it sinks to the bottom with a constant velocity equal to the velocity with which it hit the foam. The ball reaches the bottom 4.20 s after it is released. How deep is the vat?

A ball is dropped from a rocket that is 350 m above the ground and rising at 18 m/s. ( We choose the origin to be at ground level and neglect the air resistance.) (a) What is the maximum height that the ball reached? (b) What are the position and the velocity of the ball after being released for 4s? (c) What is the total time the ball taken to hit the ground?

A swimmer dives from a diving board 15.0 m above the water's surface. his initial velocity is 2.10 m/s at an angle of 32.0 degrees above the horizontal. a) How long does it take him to hit the water? b) When he hits the water, what is the magnitude of his displacement from the diving board? Thank you!

2. A diver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. She starts with a velocity of 4.00 m/s upward, and her takeoff point is 1.80 m above the pool. (a) What is her highest point above the board? (b) How long a time are her feet in the air? (c) What is her velocity when her feet hit the water?

A ball is thrown off a cliff overlooking a lake. The cliff is 9.60 m above the lake. The ball has an initial speed of 2.85 m/s and is thrown at an angle of 20.0° below the horizontal. (a) Calculate the time after the ball is thrown until it strikes the water. (b) Calculate the ball’s speed just before striking the water. (c) How far from the base of the cliff does the ball hit the lake? (d) Sketch the...

A boy stands on a diving board and tosses a stone into a 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 60.0° 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 the water. After the stone enters the water,...

A person jumps off a diving board 3.6 m above the water's surface into a deep pool. The person's downward motion stops 1.9 m below the surface of the water. A. Estimate the average deceleration of the person while under the water. Express your answer to two significant figures and include the appropriate units.
