Question 1
Two cars accelerate from zero initial velocity and
travel the same time. Acceleration of the Car #1 is
twice smaller than acceleration of the car 2. The
displacement from the original position for car # 2
as compared to the displacement for the car #1 is:
a) The same
b) Twice larger
c) Twice smaller
d) Four times larger
e) Four times smaller
Period 2
Question 2

b) It can either be at rest or move with
constant velocity
c) It will move with a constant acceleration
d) None of the above

Question 1
A boat moves through the water in a river at a
speed of 8m/s relative to the water. The boat makes
a trip downstream and then makes a trip upstream
to the original starting point. Which trip takes
longer?
a) The downstream trip
b) The upstream trip
c) Both trips take the same time
d) The answer cannot be figured
without knowing the speed of the
river flow
Period 3
Question 2
The earth exerts a gravitational force on a
raindrop, pulling it down. Does the raindrop
exert a gravitational force on the earth?
a) No, it does not, since the earth is not moving
towards the drop
b) Yes, but the drop attracts the earth with
much smaller force than the earth attracts
the drop
c) Yes, and the force acting on the earth is
equal in magnitude to the force acting on
the drop
d) The raindrop will exert a force on the earth
only at the moment when it touches the
earth surface
