Electrostatic potential energy:
Law of conservation of energy:
Wnc is the work done by non-conservative forces like friction.
Ki + Ui + Wnc = Kf + Uf
(1/2)mv02 + kq1q2/ri + 0 = (1/2)mvf2 + kq1q2/rf
A proton follows the path shown in (Figure 1) . Its initial speed is v0 = 2.9×106 m/s. What is the proton's speed as it passes through point P? Express your answer to two significant figures and include the appropriate units.
