Basic kinematics variables: A racing car accelerates uniformly from rest along a straight track. This track has markers spaced at equal distances along it from the start, as shown in the figure. The car reaches a speed of 140 km/h as it passes marker 2. Where on the track was the car when it was traveling at 70 km/h?
A) Before marker 1
B) At marker 1
C) Between marker 1 and marker 2
