For the vectors in the figure, with a = 12, b = 9.0, and c = 15 what are (a) the magnitude and (b) the direction of a* b, (c) the magnitude and (d) the direction of a * c , and (e) the magnitude and (f) the direction b * c?

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

If y gets smaller as x gets bigger and y have an relationship?
