F = F⁰ - Ff

F = 360 N - 340 N

F = 20 N

F = m × a

20 N = 50 kg × a

a = 20 N / 50 kg

a = 0.4 m/s²

Answer:

$C=2.54\cdot 10^5\ F$

Explanation:

<u>Energy Stored on a Capacitor</u>

This energy is stored in the electric field present when a voltage V is applied to a capacitor C. It can be computed by the formula

$\displaystyle E=\frac{CV^2}{2}$

We can compute the energy by knowing the power dissipated in the flashlamp is P=8 W in a time of $7 \mu s=7\cdot 10^{-6}\ sec$

$\displaystyle E=\frac{P}{t}=\frac{8\ W}{7\cdot 10^{-6}\ sec}=1.14\cdot 10^6\ J$

Solving the first equation for C

$\displaystyle C=\frac{2E}{V^2}$

$\displaystyle C=\frac{2\times 1.14\cdot 10^6}{3^2}$

$\boxed{C=2.54\cdot 10^5\ F}$

Four red flags

The load being carried poses a hazard to vehicles in the proximity of the load-carrying vehicle, and so it is mandatory by law for the vehicle to make the load more visible. At night time, the load is marked using red lights, as flags would not be visible then.
