A proton is flying through space with an initial velocity v0 = 3.6×106 m/s, as shown below. It interacts with a fixed negative charge q = −13 nC along the path shown. What is its speed in m/s when it reaches the point P. given that x = 2.8 cm and y = 5.7 cm? Give your answer to 3 significant digits. (note the drawing may not be to scale)
