travelled along a straight road. Give reasons for your answers to
these questions:
(a) Which car was travelling at a steady speed?
(b) Which car was decelerating?
(c) Which car had the greatest acceleration
(a) The car that was traveling at a steady speed can be determined by looking at its velocity-time graph. If the graph shows a straight, horizontal line, it indicates that the car's velocity is constant and, therefore, it is traveling at a steady speed.
(b) The car that was decelerating can be determined by analyzing its velocity-time graph. If the graph shows a decreasing slope, it means that the car's velocity is decreasing over time, indicating deceleration.
(c) The car with the greatest acceleration can be determined by examining its velocity-time graph. If the graph shows a steep slope, it indicates that the car's velocity is increasing rapidly over time, implying a greater acceleration.
