A housefly with a mass of 0.00100 kilograms zooms through the room at a rate of 2.20 m/s. How much kinetic energy does it have
Answer:
Kinetic energy, KE = 0.00242 J
Explanation:
It is given that,
Mass of housefly, m = 0.00100 kg
The housefly is moving at the rate of 2.20 m/s i.e.
v = 2.20 m/s
We have to find the kinetic the of the housefly. The housefly is moving inside the room so it will have kinetic energy and it is given by :
\(KE=\dfrac{1}{2}mv^2\)
\(KE=\dfrac{1}{2}\times 0.00100\ kg\times (2.20\ m/s)^2\)
KE = 0.00242 J
Hence, the housefly will have energy of 0.00242 J
