You see a squirrel running on a direct line from you. You estimate that its velocity can be described by the function v(t)=2t²-3 with positive values representing "away from you." You estimate that the squirrel began 2 meters in front of you.
a. What are the units associated with the coefficients "2" and "3"?
b. What is the magnitude and direction of the squirrel’s initial velocity?
c. How fast is the squirrel going at t=3 s?
d. What is the squirrel’s acceleration at t= 3 s?
e. Where is the squirrel at t= 3 s?
f. At what time does the squirrel temporarily stop moving?
