The following diagrams indicate a photographic record of the motion of a sphere in five different scenarios. The motion of the ball is from left to right in each scenario. The time interval between each successive position of the sphere is the same in every case. However, the number of pictures taken in each case is not the same. Please remember that negative numbers are smaller than positive numbers Al Average Speed In which scenario does the sphere have: 1....
