Question

Please show me how to get the 4 amount of times from this graph! Thank you! I know its delta x/t but I can't seem to do it right or get the right answers.

displacement occurs, which can be written as TACTICS BOx 2.1: Interpreting position-versus-time graphs Information about motion can be obtained from position-versus-time graphs as follows: At 1. Determine an object's position at time t by reading the graph at that instant of time 2. Determine the object's velocity at time t by finding the slope of the position graph at that point. The magnitude of the This equation has a graphical interpretation: It tells us that is the slope of the position-versus-time graph representing the motion. This implies that you can associate the slope of the graph, a geometrical quantity, with the physical quantity velocity. This and other aspects of interpreting position-versus-time graphs are outlined in the following Tactics Box. velocity is defined as speed. Steeper slopes correspond to faster speeds. 3. Determine the direction of motion by noting the sign of the slope. Positive slopes correspond to positive velocities and hence, to motion to the right (or up). Negative slopes correspond to negative velocities and, hence, to motion to the left (or down).

Explanation / Answer

x1 = 5m (at t = 2 s)

x2 = 7m (at t = 4 s)

x3 = 9 m (at t = 13 s)

x4 = 0 m (at t = 17 s)
