012 (part 1 of 2) 10.0 points A runner is jogging in a straight line at a

steady v = 4.6 km/hr. When the runner is

L= 3 km from the finish line, a bird begins

flying straight from the runner to the finish

line at vý= 9.2 km/hr (2 times as fast as the

runner). When the bird reaches the finish

line, it turns around and flies direztly back to

the runner.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
