he accompanying figure shows the position versus time curve for a certain particle moving long a straight line. Estimate each of the following from the graph: 20 Remember: Velocity is just the rate of 15 change of the position. Since this graph is the particle's position, the instantaneous velocity is just the slope at a particular t- Distance (cm) 10 value. 5 0 1 2 3 4 5 6 7 8 Time (s) Find the average velocity over the interval 0 S t $ 3. (change in position from 0 to 3 econds) The values of t at which the instantaneous velocity is zero. The instantaneous velocity at t = 3 seconds
