2. a 3.0 kg block rests on a level surface. the coefficient of static friction is µs = 0.50, and the coefficient of kinetic friction is µk = 0.20. a horizontal force f is applied to the block. as f is increased, the block begins moving. describe how the force of friction varies as f increases from the moment the block is at rest to when it begins moving. indicate how you could determine the force of friction at each value of f—before the block starts moving, at the point it starts moving, and after it is moving. show your work.

(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.)
