(a) Suppose the displacement of an object is related to time

according to the expression x = Bt^{2}. What are the dimensions

of B? (b) A displacement is related to time as x= A sin (2*π*ft),

where A and f are constants. Find the dimensions of A. Hint:

A trigonometric function appearing in an equation must be

dimensionless.

Step 1

(a) The dimension of B given...
