Homework Statement
An atom confines electrons to be within a certain region of space. Use this fact to estimate the energy of electrons in atoms and compare it to those predicted by Bohr theory, remarking on any differences or similarities.

Schrodinger's Wave Equation...
The maximum range that can be achieved will be done so when the ball is projected at an angle of 45 degrees to the horizontal. At this angle, both the horizontal and vertical velocities will be equal to 39.9*cos(45).
First, you should calculate the total time for which the ball is in the...
Try calculating the vertical speed of the rock after a time of 2.1 seconds.
Combine this vertical component of the velocity with the horizontal component given in the question. You may want to draw a quick right-angled triangle with one side equal to the horizontal component and another equal...
The initial speed, u, is 330m/s, the final speed, v is 0 m/s since the bullet comes to rest. The bullet travels a distance, s of 0.25m.
The equation of motion v^2=u^2 +2as should be of help.
Note that this will give you a negative acceleration which is to be expected as it is opposing the...
