Scientists design a new particle accelerator in which protons (mass 1.7 1027 kg) follow a circular trajectory given by r =ccos(kt2)^+csin(kt2)^, where c = 3.0 m and k = 8.0 104 rad/s2 are constants and t is the elapsed time.

Part C

What is the force on the proton at t = 3.0 s ? Give your answer in component form.
