A firecracker explodes into three parts. A 6.02g portion goes directly East at 1.46m/s and a 4.76g portion flies directly South at 1.59m/s. What is the direction of the third portion which has a mass of 4.22g?
Answer 4.96x10^1 Degrees W of N
I have worked this question out myself and come up with 49.26818444 Degrees W of N. I'm off by a very small amount but I'm not sure if I did something wrong.
My work is shown on the attached image. Please let me know where I went wrong. Thanks.
