Part C Find the dimensions [v] of speed. Express your answer as powers of length (/), mass (m), and time t View Available Hint(s) 11에 Submit There are three dimensions used in mechanics: length (), mass (m), and time (t). A combination of these three dimensions suffices to express any physical quantity, because when a new physical quantity is needed (e.g., velocity), it always obeys an equation that permits it to be expressed in terms of the...
