Please select all that are correct. Select one or more: a. Halving the time the force is applied on an object doubles the impulse b. When the law of conservation of momentum is concerned, a pile of sand cannot be used as a closed system because the grains of sand do not stick together and there are too many of them c. If two trucks (same model) are driving with the same velocity, the empty truck has less momentum than the truck fully loaded with rubber ducks d. A snowball is thrown on a wall. It bounces off, but leaves a white mark behind. This is neither a perfect elastic collision, nor a perfect inelastic collision If a cup of hot coffee is defined as a closed system, then the steam coming off the surface has to be accounted for as part of the system e. f. Having a pie thrown on one's face is an example of an inelastic collision g. Law of conservation of momentum only works in 1D and 2D, but no higher h. When two figure skaters (one going SouthEast, the other going NorthEast) clasp hands, they begin moving West before having to apply a force on the ice i. Velocity, momentum, and impulse can all be expressed in terms of their x-, y-, and z- components
