Reinforcement Question Chapter 2: Kinematics
1.
Two cars, a Porsche and a Honda, are traveling in the same direction, although the
Porsche is 186 m behind the Honda. The speed of the Porsche is 24.4 m/s and the
speed of the Honda is 18.6 m/s. How much time does it take for the Porsche to catch
the Honda?
2. a) The figure next shows the
vertical velocity component
of an elevator versus time.
If the elevator starts to
move at
t
= 0 s, when is
the elevator at its
highest location above
the starting point ?
b) How high is the elevator
above the starting point,
t
= 0 s, after 20 s have
elapsed?
3. The figure next shows a
graph of speedometer readings
obtained as a car comes to a stop
along a straightline path. How far
does the car move between
t
= 0
and
t
= 16 s?
4. The figure below shows a graph of
x
(
t
) in meters, on the vertical axis, for an object
traveling in a straight line.
(a) What is
for the interval from
t
= 0 to
t
= 4.0 s?
(b) What is
for the interval from
t
= 0 to
t
= 5.0 s?
(c) What is
v
x
at
t
= 2.0 s?

5. An object is moving along a straight line.
The graph in the figure next shows its
position from the starting point as
a function of time.
(a) In which section(s) of the graph does
the object have the highest speed?
(b) At which time(s) does the object
reverse its direction of motion?
(c) How far does the object move from
t
= 0 to
t
= 3 s?
6. A motor scooter travels east at a speed of 12 m/s. The driver then reverses direction
