Question

A horizontal rifle is fired at a bulls-eye. The muzzle speed of the bullet is 680m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.025 m below the center. What is the horizontal distance between the end of the rifle and the bulls-eye A puck is moving on an air hockie table. Relative to an X, Y cordinate system at time t = 0 seconds, the x component of the puck's initial velocity and acceleration are Vw = +2.6 m/s and a = +6.5 m/s². The y components of the pucks initial velocity and acceleration are Voy = +8.6 m/s and A. = 7.4 m/s². Find @ the magnitude v and 6 the direction o of the puck's velocity at a time of t=0.50 seconds. Specify the direction relative to the +X axis A tennis ball is struck and departs horizontally from a the raket with a speed of 27.3 m/s. The ball hits the court at a horizontal distance of 18.3 m from the raket. How for above the court is the tennis ball when it leaves the raket?
