A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 2.8 m above the water surface with a velocity of 7.37 m/s at an angle of 60.0° above the horizontal. Determine the horizontal distance the stone travels before it strikes the water. Answer: Check
A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 3.67 m above the water surface with a velocity of 5.35 m/s at an angle of 60.0° above the horizontal. Determine the horizontal distance the stone travels before it strikes the water. Answer: Check
A girl stands on the deck of the boat and tosses a rock into a lake. The rock is thrown from a height of 2.50 m above the water surface with a velocity of 4.35 m/s at an angle of 60.0° above the horizontal. As the rock 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 rock enters the...
The vector position of an object varies according to r(t) = (24.0 m)i + [(2.00 m/s2)t2]j, where t is in seconds. (a) Determine the magnitude of the position vector at t = 5.00 s. (b) Determine the magnitude of the velocity vector at 5.00 s. A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 2.93 m above the water surface with a velocity of 5.26 m/s...
Chapter 26, Problem 018 A stone held just beneath the surface of a swimming pool is released and sinks to the bottom at a constant speed of 0.34 m/s. What is the apparent speed of the stone, as viewed from directly above by an observer who is in air? Take the refraction index of water to be 1.333.
To a person swimming 0.815 m beneath the surface of the water in a swimming pool, the diving board directly overhead appears to be a height of 5.00 m above the swimmer. 1.) What is the actual height of the diving board above the surface of the water?

Problem 4: At a local swimming pool, the diving board is elevated h = 9.5 m above the pool's surface and overhangs the pool edge by L = 2 m. A diver runs horizontally along the diving board with a speed of vo = 4.8 m/s and then falls into the pool. Neglect air resistance. Use a coordinate system with the horizontal x-axis pointing in the direction of the diver's initial motion, and the vertical y-axis pointing up....
A boy stands at a dark well and wants to investigate how deep this well is. He therefore throws a stone into the well and after 2.6 seconds he hears the sound of the stone hitting the water surface. If the sound velocity is assumed infinitely high and it is assumed that one can ignore the air resistance of the stone. Sound speed at sea level is approximately 340 m / s. Approximately how large a deviation from the above...
A person is swimming 0.91 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.4 m above the water. From what height was the ball actually dropped?
A person is swimming 0.87 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.3 m above the water. Part A From what height was the ball actually dropped?
