A mass spectrometer has an adjustable magnetic field. When the magnetic field is 7.000e-2 T, a singly ionized hydrogen atom (a proton) will strike the detector at a particularlocation. Suppose a triply-ionized carbon 12 atom, whose mass is by definition 12 u (where1 u = 1.66×10−27 kg) enters the spectrometer at the same speed as the proton. What is the strengthof the magnetic field that will cause it to strike the detector atthe same location as the proton?

While running, a person dissipates about 0.524 J of mechanical energy per step per kilogram of body mass. If a 65.5 kg person dissipates a power of 76.6 W during a race, explain how fast is the person running?
A 3 kg block moving at 4 m/s makes a head-on elastic collision with a stationary block of mass 2 kg. Use coservation of momentum and the fact that the relative speed of recession equals the relative speed of approach to find the velocity of each bloc..
