I know the equation is lim (change in t->0) (change in v/change in t) which equals (dv)/(dt)

I am unsure how to do derivatives.

For the problem that I am working on....

change in time = 5.53 s

change in velocity = 54.25m/s

I feel really dumb, but for wnatever reason I forgot how to do the following equation....

(3.30cm) x (cos 60.0degrees)

the answer is 1.65cm but I cannot figure out how to get this answer.

The position of a particle for the time interval t=0.000s to t=3.00s is given by

x(t) = (2.00m/s^3)t^3 - (4.00 m/s^2)t^2 + (2.00m/s)t

(a) At what time(s) between t=0 and t=3.00 is the particle at reast?

(b) For each time calculated in part (a), is the acceleration of the particle positive or negative?

(c) Find the maximum velocity of the particle

Any help is appreciated! Thanks!

We recently rescued a male puppy from a home where they were keeping at least 50 dogs cages up without food or water. Being that he had such a background, we are unsure what he is exactly. Some people say Jack Russell, others say Pitbull. Actually the 2 vets at the office do not agree...one says he is straight up Pitbull and the other says he is a terrier mix w/o any pitbull in him.

He is approximately 3 months old and 13 pounds. Any ideas?

I have a crazy schedule between work and school that I have no time to stop and eat between 2pm and midnight...I have about 2 minutes between classes and you can't eat IN class. I get home around midnight, so is it better to just not eat, or actually eat dinner when I get home....I'm usually STARVING by then!!
