The energy stored in a capacitor is given by
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.
Let's calculate the energy of the first capacitor:
And now the energy of the second capacitor:
So, the total energy stored in the two capacitors is
where C is the value of the capacitance while V is the voltage difference applied to the capacitor.

Answer:
Top speed is 31.68 m/s
Explanation:
Speed of a body is the distance traveled by the body in unit time.
Speed is generally expressed in meter per second or kilometer per hour.
Here, the cheetah travels a distance of 274 m in 8.65 s.
Therefore, speed of cheetah is the distance traveled by it in one second.
For 8.65 s, distance traveled is 274 m
For 1 s, distance traveled will be meters per second. This value is called speed.
So, speed is given as the ratio of the distance traveled to that of the time taken.
∴ Top speed of cheetah is given as:
Here, is the top speed of cheetah.
