A position-time graph for a particle moving along the x axis is shown in the figure below. x (m) 2 3 4 5 6 (a) Find the average velocity in the time interval t = 2.00 s to t = 4.00 s. (Indicate the direction with the sign of your answer.) -3.5 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s x (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.) 4 x The response you submitted has the wrong sign. m/s (c) At what value of t is the velocity zero?
