Q. Each of the three graphs represents acceleration versus time for an object that already has a positive velocity at time Which graphs show an object whose speed is increasing for the entire time interval between $t_1$ and $t_2$ ?Physics Question Image

Motion in a Straight Line

Solution:

Acceleration is positive in all three graphs, so velocity increases in all three.
