Concept explainers
Automobile Velocity Two cars start from rest at a traffic light and accelerate for several minutes. The graph shows their velocities (in feet per second) as a function of time (in seconds). Car A is the one that initially has greater velocity. Source: Stephen Monk.
a. How far has car A traveled after
b. When is car A farthest ahead of car B?
c. Estimate the farthest that car A gets ahead of car B. For car A, use formulas from geometry. For car B, use
d. Give a rough estimate of when car B catches up with car A.
