4. Two cars are traveling, one behind the other, on a straight road. Each has a speed of 70 ft/sec and the distance between them is 90 ft. The driver of the rear car decides to overtake the car ahead and does so by acceleration at 6 ft up to 100 ft/sec after which he continues at this speed s2 until he is 90 ft ahead of the other car. a) How far does the overtaking car travel along the road between the beginning and end of this operation? b) If a third car were in sight, coming in the opposite direction at 88 ft/sec, what would be the minimum safe distance between the third car and the overtaking car at the beginning of the overtaking operation?

4. Two cars are traveling, one behind the other, on a straight road. Each has a speed of 70 ft/sec
and the distance between them is 90 ft. The driver of the rear car decides to overtake the car
ahead and does so by acceleration at 6
ft
up to 100 ft/sec after which he continues at this speed
s2
until he is 90 ft ahead of the other car.
a) How far does the overtaking car travel along the road between the beginning and end of
this operation?
b) If a third car were in sight, coming in the opposite direction at 88 ft/sec, what would be
the minimum safe distance between the third car and the overtaking car at the
beginning of the overtaking operation?
