New to PF, so here it goes. Oh just a question, did this site use to have a dark skin? I can't remember if that was this or something else.
The position of a particle as a function of time (in s) is given by C1 + C2t + C3t2. Let C1 = 11.0 m, C2 = 9.5 m/s and C3 = -0.49 m/s2. What is the velocity of the particle at time t = 15.0 s? And what is the particle's acceleration at time t = 15.0 s?
Velocity is the derivative of position.(How do you make it look all nice?)
Acceleration is the 2nd derivative of position.
Where do I start? I don't even understand the equation that's given. Judging from the question (it's online) it looks like those t are variables and not subscripts.
