General Physics :: Projectile Motion :: How to Calculate #1

Problem #1: To find out where the cannon ball will land, given the initial velocity ( v_{0}) and the firing angle (θ_{0}) (The parameters whose values are known are highlight in red. The main direction of solving a problem: try to derive equations that use these parameters with known values.)

Solution Step-by-step:

Try it: Change the values for v_{0} and θ_{0} in the equations below, and then click the Calcuate button to calcuate the v_{x0} and v_{y0}:

v_{x0} = v_{0} × cos θ_{0} v_{x0} = m/sec. × cos (degree) = 6.928 m/sec. v_{y0} = v_{0} × sin θ_{0} v_{y0} = m/sec. × sin (degree) = 4 m/sec.
