Answer:
[tex] \huge{ \boxed{ \bold{ \sf{90 \: joule}}}}[/tex]
✑ First , Let's know what kinetic energy is :
⇾ The energy possessed by a body by the virtue of it's motion is called kinetic energy of the body. A flying bird , a moving car , running water , wind , a bullet fired from a gun , an arrow left from a bow , rolling stone etc are some examples of kinetic energy.
The Kinetic energy of a moving body is determined by the formula :
[tex] \boxed{ \underline{ \sf{KE= \frac{1}{2} m {v}^{2} }}}[/tex]
Here ,
- m = mass of the body
- v = velocity of the body
--------------------------------------------------------------
☇ Now , Let's solve :
☄ Given :
- Mass of the object ( m ) = 20 kg
- Velocity of the object ( v ) = 3 m/s
☄ To find :
- Kinetic energy of the object
⤿ [tex] \boxed{ \sf{KE= \frac{1}{2} m {v}^{2} }}[/tex]
Plug the values and simplify :
→ [tex] \sf{ \frac{1}{2} \times 20 \times {(3)}^{2} }[/tex]
→ [tex] \sf{ \frac{1}{2} \times 20 \times 9}[/tex]
→ [tex] \boxed{ \bold{\sf{90 \: joule}}}[/tex]
Hope I helped !
Have a wonderful day ! ツ
