3）?An object with initial velocity v0, as shown above, slides up and then down a long, frictionless, inclined plane. Which of the following is true of the object as it moves?

1. It has a constant acceleration while moving up the plane and a greater acceleration when moving down the plane.
2. It has a constant acceleration while moving up the plane and a smaller acceleration when moving down the plane.
3. It moves with a constant velocity both up and down the plane.
4. It has the same acceleration as it moves up and down the plane.
5. It has a continually varying acceleration as it moves up and down the plane.

9）An object moving on a horizontal, frictionless surface makes a glancing collision with another object initially at rest on the surface. In this case which of the following is true about momentum and kinetic energy?

1. Momentum is always conserved, and kinetic energy may be conserved.
2. Kinetic energy is always conserved, and momentum may be conserved.
3. Momentum is always conserved, and kinetic energy is never conserved.
4. Both momentum and kinetic energy are always conserved.
5. Neither momentum nor kinetic energy is conserved.

18）Identical net forces act for the same length of time on two different spherical masses. Which of the following describes the change in linear momentum of the smaller mass compared to that of the larger mass?

1. It is smaller than the change in linear momentum of the larger mass but not zero.
2. It is larger than the change in linear momentum of the larger mass.
3. It is equal to the change in linear momentum of the larger mass.
4. It is zero.
5. It depends on the relative diameters of the two masses.
