Calculus Based Physics Help Please:
Suppose the position vector for a particle is given as a function of time by r hat of t = x(t) i hat + y(t) j hat while x(t)=at+b and y(t)=c(t^2)+d, where a=1.00 meters/sec, b=1.00 m/s, c=0.125 m/s and d=1.00 m.. What is the average velocity during the interval 2.00 seconds to 4.00 seconds?
What is the velocity and speed at t=2.00 seconds?
