A car, just pulling onto a straight stretch of highway, has a constant acceleration trom 0 m/s to 25 m/s west in 12 . aDraw a v-t graph of the car's motion, b. Use the graph to determine the car's displacement during the 12.0-time interval Another car is traveling along the same stretch of highway. It traveis the same distance in the same time as the first carbut its velocity is constant. Draw a v-t graph for this car's motion. dExplain how you knew this car's velocity.

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?
