The question is find the resultant of the vectors shown in the figure below. (Take a = 20.8°, b = 54.0° and c = 29.7°.) I got the resultant vector to be 1.9units, it also tells me to find the direction counterclockwise from the positive x-axis. I'm not sure how to do that, is it asking me...

it would be 0. Oh yeah i forgot about that...so it would be (51+37.6)/1.05x10^-3

so then I would just do change in velocity which is 51-37.6 and divide that by 1.05x10^-3? that give my answer?

A baseball player hits a line drive. Just before the ball is struck, it is moving east at a speed of 37.6 m/s (84 mi/h). Just after contact with the bat, 1.05x10^-3 s later, the ball is moving west at a speed of 51 m/s (114 mi/h). Find the ball's average acceleration. So i know that to find...
