Many problems in Physics use subscripts to identify quantities. For example, many of the problems that will be considered have an 'initial' and 'final' situation. For example, "the final velocity of an object is equal to the initial velocity plus the acceleration multiplied by time." Mathematically, this is written as: vf = v; + at. There are two velocities in this equation, but the subscripts i' and 'f' indicate that they are separate %3D variables. Furthermore, the 'signs' of the variables must be consistent. And although it isn't always possible, the variable letters try to reflect the quantities they represent (v for velocity, t for time, a for acceleration, etc.). What is the final velocity of a car starting from rest with a = 1.9 and t = 4 s? Round your answer to the tenths place.
