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.
speed=0
speed = 140 km/h
Start
Marker
Marker 2
20. Where on the track was the car when it was traveling at half this speed, that
is at 70 km/h
a. Before marker 1
b. At marker 1
c. Between marker 1 and marker 2
