4. a) Find the i) dot and ii) cross products of vectors A and B? =4+2+3k and B and B = 2+5+1k - b) A cannon ball is fired with an initial velocity of 30 m/s at an angle of 45. How far away from the cannon does the ball land. 4. a) Find the i) dot and ii) cross products of vectors A and B? =4+2+3k and B and B = 2+5+1k - b) A cannon ball is fired with an initial velocity of 30 m/s at an angle of 45.
