Question
Two cars, A and B, move to the east along a straight
road.
At time t = to, car A is to the east of car B (i.e., ahead of
car B) and has speed v. Car B has speed 0.2v.

From time t = t, to time t = 2t, car A moves with
decreasing speed while car B moves with increasing
speed.
At time t = 21,, both car A and car B have speed 0.80..
a. For the small time interval from time t=t, to time t = to + At, does the distance between car A
and car B increase, decrease, or remain the same? Explain your reasoning.
b. Is the distance between car A and car B at time t = 2t, greater than, less than, or equal to the
distance between car A and car B at time t= 1.5t,? Explain your reasoning.
