A hunter points a rifle horizontally 3.30 m above the ground. The bullet leaves the barrel at 325. m/s.
 
  (a) How long did it take for the bullet to strike the ground?
  (b) How far horizontally did it travel?

Question 2

A mass is attached to a vertical spring and bobs up and down between points A and B. Where is the mass located when its kinetic energy is a maximum?
 
  A) at either A or B
  B) midway between A and B
  C) one-fourth of the way between A and B

Question 3

When the first law of thermodynamics, Q = u + W, is applied to an ideal gas that is taken through an adiabatic process,
 
  A) u = 0.
  B) W = 0.
  C) Q = 0.
  D) it is not true that u = 0 or W = 0 or Q = 0.

Question 4

A charged capacitor stores energy, and when the Teflon dielectric between the plates is pulled out the energy stored more than doubles. Where did the extra energy come from?
 
  What will be an ideal response?
