he Ashely is approaching a stoplight moving with a velocity of 30.0 m/s. The light turns yellow, and Ashley applies the breaks and skids to a stop. If her acceleration is m/s 2, then determine the distance the car traveled while skidding. WARM UP: to be done in your notebook

Acceleration and Motion Graphs

VELOCITY TIME graphs This straight line on a v/t graph means that the speed is constant and is not changing over time. A STRAIGHT LINE ON A V/T GRAPH DOES NOT MEAN THE OBJECT IS NOT MOVING. But is does mean there is NO ACCELERATION

This graph shows decreasing speed. The moving object is decelerating. SLOWING DOWN
