Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Natural forces that can alter ecosystems include seasons and climate changes. t or f

(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.)
