I am very embarrassed to ask these questions because compared to other questions on these boards, these two seem very basic. Nonetheless, I have never taking physics and I am having a hard time grasping its concepts. So here are two simple questions that maybe someone could answer and explain for me. Thanks!
1st Q: During a short interval of time the speed v in m/s of an automobile is given by v = at^2 + bt^3, where the time t is in seconds. The units of a and b should be?
2nd Q: Suppose A = B^n*C^m, where A has dimensions LT, B has dimensions L^2T^–1, and C has dimensions LT^2. Then the exponents n and m have the values:
