What graph BEST represents the relationship between velocity and time for an object that accelerates uniformly for 2 seconds, then moves at a constant velocity for 1 second, and finally decelerates for 3 seconds?

Answer 1

The best graph that represents the relationship between velocity and time for the given scenario would be a graph with three different sections:

1. The first section would be a straight line with a positive slope, representing the object's acceleration for 2 seconds.
2. The second section would be a straight line with a zero slope, representing the object's constant velocity for 1 second.
3. The third section would be a straight line with a negative slope, representing the object's deceleration for 3 seconds.

In summary, the graph would show an increasing velocity for 2 seconds, followed by a flat line representing constant velocity, and then a decreasing velocity for 3 seconds.
