a car initially traveling at 5 m/s accelerates for 2 seconds at 3 m/s. how far does it travel during this time?

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

(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.)
