The speed of a bobsled is increasing, because it has an acceleration of 2.44 m/s2. At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 595 N. The mass of the bobsled and its riders is 315 kg. (a) What is the magnitude of the force propelling the bobsled forward

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
