Started over. Back to vectors. v =.26[cos 60i+sin 60j) = .13i+.22j (this is instantaneous velocity). avg a = delta v/delta t = (.13i+.22j-.26i)/300 = (-.13i+.22j)/300 = (-4.3i+8.7j)10^-4 - this is closer, but magnitude of a would be 9.7(10)^-4 ... which is way off from 9(10)^-4. Almost there ... kinda/sorta. Comments?
