- A projectile is fired from ground level above the horizontal on an airless planet where g = 10m / s * 2 The initial x and y componentFor women’s volleyball the top of the net is 2.24 m above the floor and the court measures 9.0 m by 9.0 m on each side of the net. Using a jump serve, a player strikes the ball at a point that is 3.0 m above the floor and a horizontal distance of 8.0 m from the net. If the initial velocity of the ball is horizontal, (a) what minimum magnitude must it have if the ball is to clear the net and (b) what maximum magnitude can it have if the ball is to strike the floor inside the back line on the other side of the net?A dive-bomber has a velocity or 280 m/s at ail angle below the horizontal. When the altitude of the aircraft is 2.15 km, it releases a bomb, which subsequently hits a target on the ground. The magnitude of the displacement from the point of release of the bomb to the target is 3.25 km. Find the angle .
- A rugby player runs with the ball directly toward his opponent’s goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball’s velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity relative to himself. If has magnitude 6.0 m/s, what is the smallest angle it can have for the pass to be legal?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…A projectile is fired at an angle above the horizontal at a location where g = 9.8 m/s2. The initial x and y components of its velocity are 86.6 m/s and 50 m/s respectively. At what angle was the projectile fired above the horizontal?
- A marble is launched from the edge of a table at a angle of 45 ° up from horizontal and goes through the air until it hits the floor. True or False? For such a marble, |vx| (the magnitude of the x-component of the velocity) is decreasing the entire time the marble is airborne.The trajectory of a projectile launched from ground is given by the equationy = -0.035 x2 + 0.75 x, where x and y are the coordinate of the projectile on arectangular system of axes. Find the initial velocity and the angle at which theprojectile is launched.When a projectile is fired with a velocity of 815 m/s at an angle of 37º above the horizontal, the maximum height reached by the projectile is what?
- In a football game, a player wants to kick the ball as far as possible, but also make sure that it stays in the air as long as possible, so that there is enough time for other players to run down the field and tackle the receiver. If the football is supposed to travel a distance of 49.8 m and stay in the air for 4.41 s, what initial angle and speed does the player have to provide? You can assume that the initial and final vertical coordinate are zero. Hint: Start from the range equation that you derived in class.A marble is launched from the edge of a table at a angle of 45 ° up from horizontal and goes through the air until it hits the floor. True or False? For such a marble, |vy| (the magnitude of the y-component of the velocity) is decreasing the entire time the marble is airborne. Group of answer choicesNeglecting the size of the ball, determine the magnitude Va of the basketball's initial velocity and its velocity when it passes through the basket, including its magnitude and direction.
