Compare these two collisions of a pe student with a wall.
case a: a 75-kg pe student moving at 8 m/s collides with a padded wall and
stops.
case b: the same 75-kg pe student moving at 8 m/s collides with an unpadded
wall and stops
which variable is different for these two cases?
which case involves the greatest momentum change?
which case involves the greatest impulse?
which case involves the greatest force?

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?
