(4-y^2)/(y-2) = y/2 (4-y^2)/(y-2) = y/2 4 - y^2 = (y*(y-2))/2 4 - y^2 = (y^2-2y)/2 8 - 2y^2 = y^2 - 2y 3y^2 - 2y - 8 = 0 (keep the above equation in mind) quadratic formula: (-b +/- sqrt(b^2 - 4ac))/2a now solve by plugging in the appropriate numbers and choose (normally) the ...

An electron passes location <0.02m, 0.04m,−0.06m>, and 4 μs later is de- tected at location <0.02 m, 1.84 m,−0.86 m>. Find the average velocity of the elecron: ¯v = <vx, vy, vz> If the electron continues to travel at this av- erage velocity, ...
