2.7 A position-time graph for a particle moving along the x axis is shown in Figure P2.7.(a) Find the average velocity in the time interval t = 1.50 s to t =4.00 s. (b) Determine the instantaneous velocity at t =2.00 s by measuring the slope of the tangent line shown Chapter 10 - VELOCITY, ACCELERATION and CALCULUS 221 0.5 1 1.5 2 t 20 40 60 80 100 s Figure 10.1:4: Keith’s regression 5. Portions of a trip to Grandmother’s look like the next two graphs.
Did you linear fit of this graph provide acceleration if yes what is its value? Yes 0.0826 m/s squared How does the time your calculated average velocity occurred at compare to the times of the two middle points from the position VS time graph
