A particle moves along the x axis accoring to the equation x=2.00+3.00t-t^2 where x is in meters and t is in time. At 3.00s what is the velocity and acceleration. For velocity, I would just take the derivative of x=2.00+3.00t-t^2 and sub in 3.00s and for the acceleration I would have to get the second derivative of x=2.00+3.00t-t^2 and sub in 3.00 seconds. Is this correct?
