Question

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 1

KE = 1/2mv^2
KE = 1/2(0.00100)(2.20^2)
KE = 0.00242

hope this helps :)

Answer 2

Kinetic energy, KE = 0.00242 J

Step-by-step 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=(1)/(2)mv^2`

`KE=(1)/(2)* 0.00100\ kg* (2.20\ m/s)^2`

KE = 0.00242 J

Hence, the housefly will have energy of 0.00242 J
