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 positive vertical velocity of 4.00 m/s, and her takeoff point is 1.80 m above the pool. How long is she in the air (in seconds)?
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?
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
A high diver leaves the end of a 4.0 m high diving board and strikes the water 1.5 s later, 2.0 m beyond the end of the board. Considering the diver as a particle, Determine the magnitude of her initial velocity, v⃗ 0. Determine the angle of her initial velocity, v⃗ 0. Determine the maximum height reached. Determine the angle of the velocity v⃗ f with which she enters the water.
please show work. 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...
