A 3.00 gram dart compresses a spring by 4.00cm. The dart lands 3.60m downrange when fired horizontally from the gun from a height of 113cm. All answers must be given in standard S. I. units as a number without units, using precisely 2 significant digits. (e. g. 12.0N = 12 or 0.3s = .30)

what is the air-time of the dart
what is the horizontal velocity of the dart
what is the initial kinetic energy of the dart
what is the spring constant

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

Imagine you work as a consultant, and your daily job involves listening to the constructive criticism of others. as part of your job, you must listen to opposing viewpoints to make important decisions. in this activity, you are a consulting dam engineer. you must make a decision about four different dams; should they be repaired, taken down, or left alone? you will listen to contrasting opinions about what should be done with the dams before you make the final decision. as the consulting dam engineer, what do you decide to do with this dam? explain your reasoning. by making your decision, did you support the opinions of the mayor and/or the dam safety official? why or why not?
