Three joggers are running along straight lines as follows: jogger a, with a mass of 55.2kg, is traveling along the line y=6.00m at 3.45 m/s in the positive x-direction. jogger b, with a mass of 62.4kg, is traveling at 4.23 m/s along the line x=3.00m in the positive y-direction. jogger c, with a mass of 72.1kg, is traveling at 4.75 m/s along the line x=-5.00m in the negative y-direction. what is the total counterclockwise angular momentum of the three joggers about the origin?

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
