Question

A body P has KE E . Another body Q whose mass is 9 times than P also has a KE E . Calculate the ratio of velocities of P and Q ?

Answer 1

@Yahoo!

Answer 2

Let the Mass of body p = x

mass of q = 9x\[E = \frac{ 1 }{2 } * x * v1^2\]

\[E = 1/2 * 9x * v2^2\]

Answer 3

\[\frac{ v1^2 }{ v2^2 } = \frac{ 2E }{ X } * \frac{ 9X }{ 2E }\]

Answer 4

Nw.....Just Solve..)

Answer 5

Did u understand @ashna

Answer 6

not the comment above " now just solve "

Answer 7

Did u understand???

Answer 8

you have asked me to solve , i dont know how to do that ?

Answer 9

\[\frac{ v1^2 }{ v2^2 } = \frac{ 9 }{ 1 }\]

\[\frac{ v1 }{ v2 } = 3\]

Answer 10

is it over ?

Answer 11

yup.....The ratio is 3 : 1

Answer 12

yeah .. thanks :)
