CHAPTER 2: MOTION IN ONE-DIMENSION
ONE DIMENSIONAL MOTION
Q1)
A car starts from a state of rest and drives along a level, straight road. For the first
30 s, the car speeds up with a constant acceleration of 2.50 m/s
2
, after which it
continues at the constant velocity that it has acquired for the next 5.00 minutes, at
which time the brakes are applied, and there is an acceleration of -2.2 m/s
2
until
the car stops. What is the total displacement of the car from its starting point, and
the total time of travel?

Q2)
The velocity of an object as a function of time is given by
v
=

t
2
+
5
t
−
12
m/s,
where
t
is in seconds. If the object has a position
x
= 8.00 m at
t
= 2.00 s, what is
the position of the object at time
t
= 5.00 s?
