The figure shows the path of a particle that moves with position vector r(t) at time t.
(a) Draw a vector that represents the average velocity of the particle over the time interval 2 < t < 2.4.
(b) Draw a vector that represents the average velocity over the time interval 1.5 < t < 2.
(c) Write an expression for the velocity vector v(2).
(d) Draw an approximation to the vector v(2) and estimate the speed of the particle at t = 2.
