A student decides to measure the muzzle velocity of a pelletshot from his gun. He points the gun horizontally. He places atarget on a vertical wall a distance x away from the gun. thepellet hits the target a vertical distance below the gun.
(a) Showthat the position of the pellet when travelling through the air isgiven by y=Ax^2, where A is a constant.
(b) Express the constant Ain terms of the initial (muzzle) velocity and the free-fallacceleration.
(c) If x=3.00m and y=0.210m, what is the initial speed of the pellet?
