Question

what happens to the kinetic energy when mass is tripled ??
KE =1/2 M V sq
KE = 1/2 3 M V sq
ISKA AAGE KYA KARNA HAI???
KOI BATAYEGA PLZ​

Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

We know that :-

$\LARGE{\boxed{\boxed{\sf{K.E \: = \: \frac{1}{2}MV^2}}}----(1)}$

Where,

M is mass of object.

V is velocity

K.E is Kinetic energy

===================================

If Mass is tripped.

Then,

M' = 3M

Put Value in (1)

We get,

$\LARGE{\boxed{\boxed{\sf{K.E \: = \: \frac{1}{2}3MV^2}}}---(2)}$

______________

Divide (2) by (1)

$\Huge{\boxed{\boxed{\sf{\frac{K.E'}{K.E} \: = \: \frac{ \frac{1}{2} 3mv^2}{ \frac{1}{2}mv^2 } }}}}$

Now,

$\Huge{\boxed{\boxed{\sf{K.E' \: = \: 3 \: \times \: K.E}}}}$

If mass is trippled than Kinetic energy will be 3 times
