Question

two bodies of equal masses moves with the uniform velocity v and 3v respectively. find the ratio of their kinetic energy​

Answer 1

Answer:

ratio of KE= 1*1/3*3= 1/9

Answer 2

Answer:

1:9

Explanation:

kinetic energy = 1/2 mv²

for body 1 K.E= 1/2 mv²

for body 2 K.E = 1/2 m9v²

thus for ratio

=

$\frac{ \frac{1 \times m {v}^{2} }{2} }{ \frac{1 \times m \times 9 \times {v}^{2} }{2} }$

= 1:9

hope it helps :)
