A proton moves through a uniform magnetic field given by B = (15.01 - 25.4) + 12.7k) mT. At time t, the proton has a velocity given by = v1 + v,+ (1.94 km/s)k and the magnetic force on the proton is FB = (5.33 x 10-17 N)i + (3.15 x 10-7N)). (a) At that instant, what is vx? (b) At that instant, what is vy? (a) Number i Unit
