The mass of a particle is frequently expressed in units of MeVie. You cle is frequently expressed in units of Meyle You can do this for the cases above by just converting Joules to MeV to get the energy in Mey. The mass is just stated as that over e-squared rather than actually doing the division by (3x10'). a) Rest mass for an electron in MeV/c. b) Find the relativistic mass of the muon from the previous section in units of MeVic 4) A photon is a massless particle that has energy and momentum. a) Using the relations above, what is the relation between total energy and momentum for the photon

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
