Ahousefly 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?

The correct answer to the question is i.e the kinetic energy of the housefly is  

CALCULATION:

As per the question, the mass of housefly m = 0.00100 kg,

The speed of the housefly v = 2.20 m/s.

We are asked to calculate the kinetic energy of the housefly.

The kinetic energy of a body having mass m and moving with velocity v is calculated as -

                      Kinetic energy K.E =

Hence, the kinetic energy of the housefly is calculated as -

                                 K.E =

                                       =

                                       =

                                      =     [ANS]

Here, joule ( J) is the unit of energy.

Hence, the kinetic energy of the housefly is  

gravitational energy

electrical energy

kinetic energy

ligh energy
