44. We assume there are no forces or force-components along the x direction. We combine Eq. 22-28 with Newton’s second law, then use Eq. 4-21 to determine time t followed by Eq. 4-23 to determine the final velocity (with – g replaced by the a y of this problem); for these purposes, the velocity components given in the problem statement are re-labeled as v 0 x and v 0 y respectively. (a) We have /( / ) aq Em emE == GG G which leads to 19 2 13 31 1.60 10 C N ˆˆ 120 j (2.1 10 m s ) j.
