Use the position function to find the velocity at time  Assume units of feet and seconds.  
A) ft/sec 
B) ft/sec 
C) ft/sec 
D) ft/sec

Quizplus · Accepted Answer

To find the velocity, we need to take the derivative of the position function. Without knowing the specific position function, we cannot calculate the answer exactly. Therefore, all we can do is choose the best option based on the given information. Since the units for position are feet and seconds, the units for velocity must be feet per second. Only choice C has the correct units, so it is the best choice.
