部分真題預(yù)覽：

11）The car is now going around a banked curve, as shown in the figure above. The banked curve is higher toward the outside of the circular turn. The car can now travel at a higher speed without sliding because the banked curve

1. increases the coefficient of friction between the car and the track.
2. increases the momentum of the car.
3. allows a component of the normal force to point toward the center of the track.
4. allows a component of the weight of the car to point toward the center of the track.
5. allows gravity to do work on the car.

14）A student pushes a box across a rough horizontal floor. If the amount of work done by the student on the box is 100 J and the amount of energy dissipated by friction is 40 J, what is the change in kinetic energy of the box?

1. 0 J
2. 40 J
3. 60 J
4. 100 J
5. 140 J

15)Three blocks of masses m, 3m, and 2m resting on a frictionless horizontal surface are connected to identical ideal springs, as shown above. A force of magnitude F directed to the left is then applied to the left end of spring A. Which spring is stretched the most when the blocks are all moving with the same acceleration?

1. A
2. B
3. C
4. None, because the springs do not stretch.
5. None, because the springs all stretch the same amount.
