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 first hits the pit? Answer = .52m I NEED TO SEE THE WORK!!

You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...
A 75-kg volleyball player performs a maximum-effort vertical jump with an initial velocity of 3 m/s. The player leaves the ground with an upright body position and also touches down with the same body position. Answer the following: ua A. How much will the player's center of mass (COM) travel in the air along the vertical direction during the ascending phase of the jump? Compute the maximum kinetic energy of the player during the jump. C. Compute the maximum potential...
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...
Anelite Basketball player has a 39 inch standing vertical, meaning that this person can jump straight upward to a height of 39 inches. (For all parts of this problem neglect air resistance) To three significant digits what is the velocity, in m/s, of the basketball player the instant leaving the ground? m/s How long total is the basketball player in the air? (round to 3 significant digits) What are the magnitude and direction of the acceleration at each instance? (Direction...
