The figure shows the y-position (in blue) of a particle versus time. y (m) 20 16 r 12 8 4 0 4 -t (s) (a) What is the average velocity of the particle during the time interval t = 0.50 s to t = 4.50 s? (Express your answer in vector form.) m/s m/s (b) Using the tangent to the curve (shown as the orange line in the figure), what is the instantaneous velocity of the particle at t= 1.50 s? (Express your answer in vector form.) ts (c) At what time is the velocity of the particle equal to zero?
