### An object moves along the x-axis. The position as a function of time is given by with

What is the object’s acceleration at time *t* = 0.50 s?

ANSWER:So, we are given a position function .

The velocity function can be determined by getting the derivative of the position function. That is

The acceleration function is the derivative of the velocity function. That is

The acceleration of the object at time t=0.50 s is
