(a) Suppose that the displacement of an object is related to time according to the expression
x = Bt^2. What are the dimensions of B?
3)L × T^2
(b) A displacement is related to time as x = A sin(2πft), where A and f are constants. Find the dimensions of A. [Hint: A trigonometric function appearing in an equation must be dimensionless.]
4)L × T
Hey guys I've used the site in the past and it has helped me tremendously. I'm now in a physics class and its going to be a long uphill struggle for me. These are 2 problems out of 15 from some homework I have and if someone can break it down for me that would be more than wonderful.
