Textbook Question
Chapter 1, Problem 23SP

A model plane flew 100 m in 25.0 s followed by another 240 m in an additional 60.0 s,

whereupon it crashed into the ground. How far did it travel in total? How long was it in

the air? What was its average speed? [Hint: The overall average is not equal to the

average of the averages. When you have several segments in a problem, label them like

this:  l 1  and  l 2  and  t 1  and  t 2 , such that  l = l 1 + l 2 and  t = t 1 + t 2 .]

Traveling with an initial speed of 70 kph, a car accelerates at 6000 km/hr2 along a straight road. How long will ittake to reach a speed of 120 kph? Also, through what distance does the car travel during this time?
A motorist has to travel 3.50km in a city where his average speed should not exceed 25km/h. If he increases his average speed 40km/h, how much time will he gain in his journey?
A driver, driving at a constant speed of 30m/s in a 50 mph zone, is unaware that he is being observed by an approaching police car (coming toward him from the front). At time t = 0, they are 800m apart and the police car has an approach speed of 40 m/s. When will the police officer catch up with the motorist? a) 80 s b) 68.6 s                            c) 11.4 s
