A. a = 9.8 m/s2 B. a = cos 30o x 9.8 m/s2 = 8.5 m/s2 C. a = sin 30o x 9.8 m/s2 = 4.9 m/s2 D. a = tan 30o x 9.8 m/s2 = 5.7 m/s2 To see the answer to today's question, visit the following link: http://mcatquestionoftheday.com/physics/acceleration-expression/<http://mcatquestionoftheday.us4.list-manage.com/track/click?u=d3318065969b7c08ead5d4c4d&id=7a3ba49d06&e=61d7ba7392>
