Question

The Problems at the end of each Chapter are ranked I, II or III according to estimated difficulty, with level 1 Problems being easiest. Level III are meant as challenges for the best students. The Problems are arranged by Section, meaning that the reader should have read up to and including that Section, but not only that Section-Problems often depend on earlier material. Next is a set of "General Problems" not arranged by Section and not ranked. Finally, there are "Search and Learn " Problems that require rereading parts of the Chapter and sometimes earlier Chapters. If you are driving 95 km/h along a straight road and you look to the side for 2.0 s, how far do you travel during this inattentive period?

Explanation / Answer

Solution:

The car is not Accelerating ; so we use the distance = speed * time .

Velocity of the car = v = 95 km/h = 95 x 1000 / 3600 m/s = 26.4 m/s

Distance traveled in the time t = velocity* time = 26.4 * 2= 52.8 m
