Unformatted text preview: v ). Remember that, during its motion, the ball is subject to a downwards acceleration, g . h L r v 39 Case 2. Now lets consider the more general case in which the gun is tilted at an angle to the horizontal. This time we need two equations: an equation that relates the muzzle velocity v to things we know or can measure, h , L , and g (see diagram). An equation that relates L to v , h , and g . The first step is to resolve the initial velocity vector into horizontal and vertical components. Then apply the equations of kinematics to both axes, remembering that only motion along the vertical ( y ) axis experiences an acceleration (due to gravity). Check your solutions by setting = 0. You should recover the solution to Case 1. h L r v...
