an obejct with an initial velocity of 14.7 m/s experiences a constant acceleration of 2.3 m/s2
for 2.5 seconds. during this time, how far does the object travel?
round your answer to the nearest 0.1 (tenths place). do not add units.

What is the radius of the circular path ofa charged particle in a magnetic field?

Which notation is used to represent an alpha particle? a. b. c. d.

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
