Question

What is the kinetic energy of a flying bird of mass 600g flying with velocity of 10m/s

Answer 1

30 J

Step-by-step explanation:

You have to transform g in kg, so 600 g=0,6 kg

the kinetic energy value is

K= ½ mv² so it is K=½ (0.6×100)=30 J

Answer 2

`\text{Kinetic energy,}\\\\~~~~~~E_k = \frac 12 mv^2\\\\~~~~~~~~~~=\frac 12 * 6* 10^(-1) * 10^2~~~~~~~;[m = 600 g = 600 * 10^(-3)~ \text{kg} = 6* 10^(-1)~ \text{kg}]\\\\~~~~~~~~~~=\frac{60}2\\\\~~~~~~~~~~= 30~ J`
