It would move at a constant speed to the right
b)
It would move right at an accelerated speed
c)
It would move right and then left
d)
It would move the direction it was kicked at a constant speed
8.
Two trucks with different masses are going down a hill. What would happen if they both applied their brakes to stop at the same time?
a)
The truck with the smaller mass will require less force to stop than the truck with the larger mass
b)
The truck with the larger mass will maintain its velocity while traveling down the hill.
c)
The truck with the smaller mass will take longer to stop than the truck with the larger mass
d)
The truck with the larger mass will have less inertia than the truck with the smaller mass.
9.

14.
You are riding a bike down a hill and the front tire falls into a large hole, When the impact causes the bike to change motion....
a)
You will continue to move in the same direction and at the same speed as before the
impact
b)
the speed of the bike always increases, giving it greater force since the mass will remain the same.
c)
your speed will increase, since now you have, not one, but two forces acting on you
d)
the bike now has a
greater overall mass - its own mass plus the mass of the object by which it has
been struck
