A particle moves along the x axis according to the equation x = 1.92 + 3.09t − 1.00t

    A particle moves along the x axis according to the equation:

    x = 1.92 + 3.09t − 1.00t2,
    Where x is in meters and t is in seconds?


    a) find the position of the particle at t=3.4s
    -I get this part. (0.866m)

    b) find its velocity at t=3.4s
    -this is where I am having trouble. I know I need to use calculus to take the derivative, but my physics class is actually ahead of my cal 1 class so I'm struggling a bit trying to conceptualize how to plug this in to the derivative definition.

    c) find its acceleration at t=3.4s

    I know its a basic problem, and you guys probably see this a lot, but I appreciate your feedback.

    Go look up how to do derivatives in your calculus text book or ask your professor.
