a horse begins 10 meters along a road from an intersection. after 6 seconds it is 80 meters further west. what is the average velocity of the horse?

The slope of a velocity time graph over any interval of time gives the during that interval

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

(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.)
