A swimmer bounces straight up from a diving board and falls feet first into a pool....
A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.00 m/s, and her takeoff point is 1.70 m above the pool. (a)How long (in s) are her feet in the air? (b)What is her highest point (in m) above the board? (c) What is her velocity (in m/s) when her feet hit the water?

A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 3.00 m/s, and her takeoff point is 1.70 m above the pool. How long (in s) are her feet in the air? What is her highest point (in m) above the board? What is her velocity (in m/s) when her feet hit the water?

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 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!

General Physics
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....

Chloe has a vertical velocity of 3 m/s when she leaves the 1 m diving board. At this instant, her center of gravity is 2.5m above the water A. How high will Chloe go? B. How long will Chloe be in the air before she touches the water? Assume that she first touches the water when her center of gravity is 1m above the water.

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,...

2.) A child stands on the end of a diving board. If the child starts the diving board bouncing down and up, it would oscillate following the equation y(t)A sin(8.4 t) with all parameters in SI units and A is the amplitude of her oscillation. a) What is the frequency of her oscillation? b) At what amplitude would the child's feet lift off of the diving board at the top of the oscillation without her pushing (or...

Gerri leaves the long jump takeoff board with a vertical velocity of 2.8m/s upward and a horizontal velocity of 7.7m/s. Gerri is in the air for 0.71 seconds before she hits the ground. Gerri’s center of gravity was 1m high (relative to the ground) at the instant of takeoff. Assume that the effect of air resistance is negligible and that the upward direction is positive. How high is Gerri's center of gravity at the end of her flight, when she...

A competitive diver leaves the diving board and falls toward the water with her body straight and rotating slowly. She pulls her arms and legs into a tight tuck position. What happens to her angular speed? -increase -decrease -stay the same -impossible to determine What happens to the rotational kinetic energy of her body? -increase -decrease -stay the same -impossible to determine
