Is having an attractive physique important? why or why not? what dangers, if any, do you see in pursuing an ideal body type? what does an ideal body type for a man or a woman look like to you? what sources in your environment and social circles influence how you define ideal body type? share a real-world story about how the pursuit of an appealing physique succeeded or failed for an individual. borrow the story from the news or share an experience of your own.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
