10-154.

An object moves along the *x*-axis with an initial position of *x*(0) = 2. The velocity of the object when *t* > 0 is given by the equation

What is the acceleration of the object when

*t*= 4?What is the total distance the object covers during the interval 0 ≤

*t*≤ 4?What is the position of the object when

*t*= 4?

This is *v′*(4).

This is *x*(4) where:

This is *x*(4) – *x*(0).
