Consider the motion of a bullet that is fired from a rifle 2 m above the ground in a northeast direction. The initial velocity of the bullet is (200,200,00. Assume the xaxis points east, the y-axis points north, the positive z-axis is vertical (opposite go, the ground is horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors for t20.
b. Make a sketch of the trajectory.
c. Determine the time of fight and range of the bullet.
d. Determine the maximum height of the bullet.

Which situation will produce the greatest change of momentum

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
