In a volleyball game held in school, Player A at position X serves the ball from a height of 1.3m from the ground, imparting it with an initial velocity at an angle of 50 degrees from the horizontal, He aimed the all to land at point O, 0.5m short to Player B, thus making an ace, Incidentally the Player B is an expert in mind reading. The instant the server hits the ball, Player B started running from rest with a constant acceleration a. Check whether the ball willclear the 2.42m high net.(answer in meters)b. At what horizontal distance in meters from position Y will Player B intercept the ball, given that he intercepts it at a height of 1.6m?c. What is the acceleration in m/s^2 of Player B
A clown juggle balls while doing other activities. In one act, she throws a ball vertically upward, and while it is in the air, she runs to and from a table 5.5 m away at constant speed of 2.5 m/s, returning just in time to catch the falling ball. With what minimum initial speed must she throw the ball upward to accomplish the act?
Consider a projectile launched form ground level at an angle of elevation with an initial velocity . The maximum horizontal range is given by xmax=(v 2/0 sin2θ)/g, where g is the acceleration due to gravity. Here is the problem: If a soccer ball is kicked from ground level with an initial velocity of 28 m/sec, what is the smallest positive angle at which the player should kick the ball to reach a teammate 48m down the field? Assume that the ball reaches the teammate at ground level on the fly. Round to the nearest tenth of a degree.
A ball is thrown into the air at 60° angle to the ground, takes a parabolic path, and is in the air for a total time of 4 s. If the upward direction from the ground is positive, what is the best estimate of the ball’s velocity at a time 3 s after it leaves the ground?
A ball is shot from the top of a building with an initial velocity of 18 m/s at an angle θ = 43° above the horizontal. If a nearby building is the same height and 61 m away, how far below the top of the building will the ball strike the nearby building? ( Choose upward as the positive y-direction and express the displacement with the sign of the result, which must be in units of meters and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m/s2.)

Miltiadis Tentoglou is the current Olympic gold medalist for the running long jump. In one of Miltiadis’ practices, he insanely attempts to jump five people who are laid out on the ground in single file from head to toe. Each of the five individuals are 1.7 meters in height and when Miltiadis launches off the ground his initial resultant velocity is directed 20 degrees above the horizon and the horizontal component of this resultant velocity is 10 m/s. In executing the jump, Miltiadis’ center of mass drops 0.6 meters vertically from the instant of takeoff to the instant of landing. Calculate Miltiadis’ a) initial and final vertical velocities in m/s, b) initial and final resultant velocity magnitudes in m/s, c) total time in the air in seconds and d) how far he was able to jump horizontally in meters. e) How many centimeters of clearance did Miltiadis have on both sides of the jump when jumping the five individuals (assume the clearance distance is the same on both sides of the…
At a track and field meet, a decathlete shotputter releases a shot at an angle of 63° above the horizontal from a vertical height of 1.8 m. What is the initial velocity of the shot, stated in Cartesian vector form, if the shot lands a horizontal distance of 20 m away? The acceleration due to gravity is 9.81 m/s?.
A projectile is launched with speed v at an angle of ?2 above the horizontal going to a maximum height NH=4.08 H.The projectile is then launched with the same initial speed but an angle of ?1 above the horizontal going to a maximum height H.Please derive the ratio of the total time of flight of the projectile as the time for launch at angle ?2 to that time at angle ?1.
The velocity of a particle is given by v ={16t^2i +4t^3j + (5t +2)k} m/s, where t is in seconds. If the particle is at the origin when t = 0, determine the magnitude of the particle’s acceleration when t = 2 s. Also, what is the x, y, z coordinate position of the particle at this instant?
A football is punted from the ground, it passes through the apex of its flight, and it begins its downward decent. When its height above the field is h = 2.5m, the horizontal and vertical components of its velocity are observed to have the values v(horizontal) = 15 m/s and v(vertical) = 2.5 m/s, respectively. Use a Cartesian coordinate system with the origin located ar the inital position of the football. Ignore air resistance. Calculare the time, in seconds, from when the football left the ground until it is descending at a height of h = 2.5m.
