Question

Two bodies of masses 2 kg and 5 kg respectively are moving at same velocity . The ratio of their kinetic energy will be​

Answer 1

Answer:

2:5 is the answer of this question

Answer 2

$\huge\color{red}\boxed{AnSWer}$

given

M1 = 2kg

M2 = 5kg

V1 = V2

so kinetic energy in M1

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

similarly k.e of m2

$\frac{1}{2} m2 {v}^{2}$

thir ratio

$\frac{ \frac{1}{2}m1 {v}^{2} }{ \frac{1}{2}m2 {v}^{2} } \\ \\ \frac{m1}{m2} \\ \\ \frac{2}{5}$

so ratio 2 : 5

• we have to find ke of both mass

• according to question velocity of objects ae equal so they will cancel out each other

• ratio of their ke will M1/M2

kinetic energy in the energy posses by the body due to motion
