How much initial velocity is necessary to hit the ball over a 10 foot fence d[xfar] feet from home plate? Assuming the simplest model for projectile motion (no wind resistance), parametric equations for the position of the ball are given by
How much initial velocity is necessary to hit the ball over a 10 foot fence d[xfar] feet from home plate? Assuming the simplest model for projectile motion (no wind resistance), parametric equations for the position of the ball are given by
Input := horiz[t_] = Vx0 t; vert[t_] = -16 t^2 + Vy0 t + h0;
We know that
Input := Vx0 = V0 Cos[theta]; Vy0 = V0 Sin[theta];
We ( reasonably ) assumed
Input := h0 = 3;
And we are told to work with theta = 25 degrees, or
Input := theta = 25 Pi/180;
