A UFO sailboat starts from rest and accelerates at a rate of 0.21 m/s^2 over a distance of 280 m. Find the boat's final velocity. *
10.8 m/s
58.8 m/s
1333 m/s
It's a UFO sailboat. Physics laws do not apply to it.

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?
