Scientists design a new particle accelerator in which protons with mass
m = 1.7 · 10-27
(kg) follow a circular trajectory given by
* = ccos(kt?)î + csin(kt²)ĵ where c = 5.0 (m) and
k = 8.0 · 104
s2
are constants and t is the elapsed time.
a) what is the radius of the circle?
b) what is the proton’s speed at t = 3.0 [s]?
c) what is the force on the proton at t = 3.0 [s]? Give your answer in component form.
