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...
Louise spikes a volleyball. At the instant the ball leaves her hand, its height is 2.6 m and its resultant velocity is 20 m/s downward and forward at an angle of 60° below horizontal. How long will it take for the ball to strike the floor if the opposing team does not block it? How far will the ball travel horizontally before it strikes the floor? Make sure to show all work.

A basketball star covers 2.65 m horizontally in a jump to dunk the ball. His motion through space can be modeled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.95 m above the floor and is at elevation 0.910 m when he touches down again. (a) Determine his time of flight (his "hang time" (b) Determine his...
Show work: 2. Convert the polar coordinates of (135m, 182 degrees) to Catesian coordinates. A. (-4.71 m, 134.9m) B. (134.9m, 4.71m) C.(-134.9m, -471m) D. (4.71 m, 134.9m) 3. A swimmer completes six laps in a 50-m swimming pool, finishing where he started. What were the linear distance and the linear displacement? A. Distance = 150 m, displacement = 150 m. B. Distance = 300 m, displacement = 300 m. C. Distance = 300 m, displacement = (0m,0m). 4. A basketball...
1. An Olympic diver drops from the 10 meter platform with an initial vertical velocity of 0.0 m/s. If the diver needs to clear the edge of the pool by 5 m, what was the horizontal velocity of the diver at the instant of takeoff? What was the horizontal velocity right before landing? (You may assume that the edge of the platform was directly above the edge of the pool.) 2. A long jumper leaves the ground at an angle...
Sin 37° 0.60 Cos 37° 0.80 Tan 37° = 0.75 Plane of Fence Fence 20 m/s 2.5 m -32 m Note: Diagram not drawn to scale. A ball of mass 0.5 kilogram, initially at rest, is kicked directly toward a fence from a point 32 meters away, as shown above. The velocity of the ball as it leaves the kicker's foot is 20 meters per second at a angle of 37° above the horizontal. The top of the fence is...

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.
