Question

You wish to take a picture of a bullet traveling at 570.0 m/s. A very brief flash of light produced by an RC discharge through a flash tube can limit blurring. Assume 1.300 mm of motion during one RC constant is acceptable, and that the flash is driven by a 650.0 uF capacitor. (a) Calculate the time for the bullet to travel the distance. (b) Calculate the resistance (in mo) of the flash tube in the circuit. ma

Answer 1

* Velocity? (v) = 570.0 m/s Distance (s) -3 = 1.300 mm = 1.3810 m т a Time (t) Velocity in = Distance Distance Velocity 1.3X10% 570 C 2.281 X 10 Seconds Time Constant (t) = RC -6 2.281 X10 t с 650X106 = 3.51 m2 RE
