- Mass of the ball, in kilograms. 
- Vector of the initial velocity, in meters per second.
- Vector of the final velocity, in meters per second.
- Impulse, in meters per second. 
, 
and 
, then the impulse delivered to the ball is:![Imp = (0.06\,kg)\cdot \left[\left(35\,\frac{m}{s} \right)\cdot (-1,0) -\left(45\,\frac{m}{s} \right)\cdot (\cos 47^{\circ}, \sin 47^{\circ})\right]](/tpl/images/1378/9347/3ccb3.png)
![Imp = (0.06\,kg)\cdot (-65.670, -32.911)\,\left[\frac{m}{s} \right]](/tpl/images/1378/9347/ecb32.png)
