SUMMARY
The velocity of an object at t=2.5 seconds can be calculated by determining the slope of the P vs T graph. The correct formula for velocity is v = d / t, but in this case, the slope method is essential. By using the coordinates (1.5, 30) and (2.5, 30), the slope is calculated as (-30 - 0) / (2.5 - 2) which results in a velocity of -60 cm/s. This method clarifies the importance of analyzing the graph's slope rather than simply dividing distance by time.
