You know that a rubber band is stretched or elongated by applied force F. The applied force F is a function of elongated amount x. This function can be described as F(x) =29*x. Now, if the rubber band is stretched 17 cm and released, what will be the velocity of the band? Assume that rubber band mass is 9 gram. Hint-use conservation of energy concept.

Is kinetic energy of a system conserved when two objects collide and stick together? What about the momentum of the system? What kind of collision is this (elastic or inelastic )?
A spherical conducting shell has 12 microcoulombs of positive charge on it. The radii of the shell are r(inner)=12 cm and r(outer)=2r(inner). A particle of -4 microcoulombs is placed at the center of the shell. Provide a sketch of the electric fie..
In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor's DNA, thus killing its cells. For one patient, it is desired that 0.10 ..
