A swimmer jumps off the board with a center of mass vertical velocity of 3.4 meters per second. The horizontal velocity of 6.8 meters of per second.
What is the swimmer's resultant velocity when the swimmer took off from the board?
What is the release angle?
What is the horizontal velocity before the swimmer lands?
If the swimmer is in the air .97 seconds, what is the horizontal displacement during the time in the air?

1) A daring 51 kg swimmer dives off a cliff with a running horizontal leap. A)What must her minimum speed be just as she leaves the top of the cliff so that she will miss the ledge at the bottom, which is L = 2.40 m wide and h = 9.40 m below the top of the cliff? 2)A physics book slides off a horizontal tabletop with a speed of 3.40 m/s. It strikes the floor in 0.400 s. Ignore...

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...

You throw an object in the air with 50 meters per second velocity and 30 degrees with respect to the horizontal direction. Calculate the displacement in the horizontal direction and how high the objects goes in the vertical direction. Assume that you climbed up a mountain that is 30 meters high and throw the object up.

A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building.
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw. Part (a) How long is the ball in the air in seconds? Part (b) what must have been the initial horizontal component of the velocity, in meters per second? Part(c)...

A skydiver jumps off of an airplane. The plane flies at an altitude of 4 km, and at a speed of 100 km/hr. The skydiver "jumps" by simply letting go of the plane and falling out. Gravity is the only thing affecting their motion until they open their parachute at a height of 2.5 km. After opening their parachute, they experience constant acceleration until they land perfectly, with...
