1. The problem statement, all variables and given/known data If speed, v, of an object depends on time, t, according to the equation v = A + Bt + Ct^4, what are the SI units of A, B, C? 2. Relevant equations v = A + Bt + Ct^4 3. The attempt at a solution For this, I've not known where to start, so I've be plugging in the variables to try to lighten the question: m/s = A + B(s) + C(s)^4 m/s = s + m/s(s) + m/s^2(s)^4 m/s^5 = s + m/s(2) + m/s^2 m/s^4 = s + m/s + m/s^2 m/s^4 = s + m/s + m m/s^2 = s + m/s m/s = s + m m/s^2 = m Obviously this is incorrect, can someone help me understand this question? I've gotten past the concepts of this question and just started mindlessly trial and error to plug in values because it's so frustrating but I cannot complete this question. Can anyone point me in the right direct? Any help is appreciated!
