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.
