15) During an equestrian show jumping competition, a rider and her horse need to jump over a fence that is 1.5 m tall. They take off from the ground with a horizontal velocity of 6.2 m/s and a vertical velocity of 2.5 m/s, giving them a projection speed of 6.7 m/s and a projection angle of 22°. The center of mass of the horse and rider is 1.94 m above the ground at the instant of takeoff, and for a...

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 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...

Simone, a 47 kg gymnast, is performing the last tumbling pass of
her floor routine. The tumbling pass involves running as fast as
possible then jumping into the air to complete a double layout with
a twist (this exact maneuver, the double layout with a twist, is
not important, but a photo is provided on Canvas to show you what
this maneuver is). The instant before she jumps into the air, her
center of mass (COM) is 0.90 m above...
