(a) Find the average velocity in the time interval t = 2.00 s to t = 3.50 s. (Indicate the direction with the sign of your answer.)
m/s
(b) Determine the instantaneous velocity at t = 2.00 s by measuring the slope of the tangent line shown in the graph. (Note that t = 2.00 s is where the tangent line touches the curve. Indicate the direction with the sign of your answer.)
m/s
(c) At what value of t is the velocity zero?
