Chapter 1, Problem 45EAP
Problems 44 through 48 show a motion diagram. For each of these Problems, write a one or two sentence “story” about a real object that has this motion diagram. Your stories should talk about people or objects by name and say what they are doing. Problems 34 through 43 are examples of motion short stories.

A spacecraft accelerates from rest: a = bt = 0.2t until a = 10.4, after which it continues at constant acceleration 10.4. Everything is in a straight line. How much time does it take to reach 10.4? (The base units are meters and seconds.) And what are the dimensions of the number b in a = bt?
A spacecraft accelerates from rest: a = bt = 0.2t until a = 10.4, after which it continues at constant acceleration 10.4. Everything is in a straight line.
a) How much time does it take to reach 10.4? (The base units are meters and seconds.)
b) what are the dimensions of the number b in a = bt?
c) a(t) = bt, with b=0.4, until a(t) = A = 9.3 , How fast is it going when the acceleration reaches A?
d) how far does the spacecraft travel during its time of variable acceleration? b=1.0 and A = 8.9.
If the distance dd (in meters) traveled by an object in time tt (in seconds) is given by the formula d=A+Bt2d=A+Bt2, the SI units of AA and BB must be
meters for both AA and BB.
m/sm/s for AA and m/s2m/s2 for BB.
meters for AA and m/s2m/s2 for BB.
m/s2m/s2 for both AA and BB.
