Assignment:
1) What are the features of the Bohr Model of the Atom (the quantum model). How do some of these features violate the predictions made by classical physics? Think about the energy levels in the atom; are there 'allowable energies' in classical physics?
2) You take one ball and throw it up into the air, and then you take a second and throw it with the same initial speed down towards the ground. Which ball hits the ground with greater total energy? Why?
an apple drops from the tree and falls freely. the apple is originally at rest a height h0 above the top of the grass
what is the ratio of the amplitude of the damped oscillations. You shoot a 58-g pebble straight up with a catapult whose spring constant is 310 N/m. The catapult is initially stretched by 0.20 m. How high above the starting point does the pebble f..
