In ice cap climates, the intense cold makes the air dry keeps the air humid promotes the formation of tundra causes great amounts of snow

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

(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.)
