A cosmic ray muon with the same charge as an electron and a mass of 1.90 x 10^-28 kg is moving toward the ground at an angle of 25.0° from the vertical with a speed of 4.90 x 10^7 m/s. As it crosses point P, the muon is at a horizontal distance of 85.0 cm from a high-voltage power line. At that moment, the power line has a current of 16.1 A.
