The freefall acceleration on the moon is 1/6 of its value on earth. suppose he hit the ball with a speed of 25m/s an angle of 30 above the horizontal. a. how long was the ball in flight?
b. how far did it travel?
c. How much farther would it travel on the moon than on earth?

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?
