(Please assume a standard Cartesian coordinate system.) Kinematics can be used to analyze an object in projectile motion. Will land when the ball is shot at an angle.ДЄs with any other situation where motion has constant acceleration, the equations of The initial velocity can then be used to calculate where the ball This can beДetermined by shooting the ball horizontally and measuring the vertical and horizontal distances Necessary to first determine the initial speed (muzzle velocity) of the ball. To predict where a ball will land when it is shot at some angle above the horizontal, it is Predict and verify the range of a ball launched at an angle Determine the initial velocity of a ball launched horizontally
