A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy
2 answers:
Answer:
<u>Kinetic energy:</u>
"The form or phase of energy which is possessed by the body due to its motion or state of its motion."
<u>As the mathematical formula for K.E energy is;</u> Explanation:
Now, we have the following data, in the given problem:
Velocity,v=4 m/s, Mass,m=7 kg, K.E=?, <u>Solution:</u> So, putting the values inside the equation(1),we will get the following answer: <u>K.E=</u> 1/2×(7)×(4),K.E=1/2×28, K.E=28/2, <u>K.E=14 Joules(or in other unit kg m²/sec²). </u>
Answer: The kinetic energy of the flying bird is 56 Joules.
Explanation:
Mass of the bird = 7 kg
Velocity of the flying bird = 4 m/s
Kinetic energy of the bird will be given by :
The kinetic energy of the flying bird is 56 Joules.
