Question

Find the Kinetic energy of the object if the mass of the object is 5 Kg

moving with a velocity of 4m/s

Answer 1

$\huge{\bf{\green{\boxed{Required\: answer→}}}}$

Kinetic energy = 40 Joule

Step by step explanation ⤵️

$\huge{\bf{\green{\boxed{GiveN→}}}}$

• Mass of object → 5kg
• Velocity of object → 4m/s

$\huge{\bf{\green{\boxed{To\: FinD→}}}}$

• Kinetic energy of the object

$\huge{\bf{\green{\boxed{Formula\: UseD→}}}}$

$\Large{\bf{\pink{[Kinetic\: Energy => \frac{1}{2} m {v}^{2} ]}}}$

Where,

• m = mass of object
• v = velocity of object

$\huge{\bf{\green{\boxed{Solving→}}}}$

we have given formula of Kinetic energy →

$\large{\bf{\green{[\frac{1}{2} m {v}^{2} ]}}}$

Substitute the values in given formula -

Kinetic energy = 1/2×5×4²

=> 1/2×5×16

=> 80/2

=> 40

Hence the kinetic energy of given object = 40 Joule.

Answer 2

Answer: ur required answer ;-

mass of object = 5kg

velocity of object = 4m/sec

;;-KINETIC ENERGY OF OBJECT = 1/2mv²

where ,

M = mass of object

V = velocity of object .

so , from the given formula

1/2mv²

kinetic energy = 1/2 ₓ 5 ₓ 4²

= 1/2 ₓ 5 ₓ16

= 80/2

= 40

hence , the kinetic energy of the given object is 40 joule ,
