A23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. the mass is pulled away from the equilibrium position (x = 0) and released. it then oscillates in simple harmonic motion with a frequency of 4.91 hz. if the mass’s maximum acceleration during the motion is 135 m/s2, how far from equilibrium was the mass initially pulled?

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?
