How long will it take a cyclist with a forward acceleration of -0.50 m/s squared to bring a bicycle with an initial velocity of forward of 13.5 m/s to a complete stop? show the formula and your work.

What will a positive and a negative charge do if they are separated from each other?

(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.)
