Question

kinetic energy of an object of mass M moving with a velocity of 5ms-1 is 25j.what will be the its kinetic energy when is velocity is doubled ? what will be its kinetic energy when its velocity is increases the three time ?​

━━━━━━━━━━━━━━━━━━━━━━

$\underline{\boxed{\bold{Answer}}}$

255J

━━━━━━━━━━━━━━━━━━━━━━

$\underline{\boxed{\bold{Explanation}}}$

$\huge\mathfrak\red{given}$

velocity of object, v=5ms-¹

kinetic of object, EK= 25J

━━━━━━━━━━━━━━━━━━━━━━

$\underline{\boxed{\bold{Formula}}}$

EK=½mv²

when velocity triples :

EK=½mv²

=½×2×(15)²

=255J

[Hope this helps you.../]

Answer 2

• velocity of object, v=5ms-¹
• kinetic of object, EK= 25J

━━━━━━━━━━━━━━━━━━━━━━

• EK=½mv²
• when velocity triples :
• EK=½mv²
• =½×2×(15)²

=255J
