(a) Suppose the displacement of an object is related to time
according to the expression x = Bt2. What are the dimensions
of B? (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
