please answer

who will answer correct i will mark as brainliest

please

i want with explaination ​

Answer 1

Answer:

t is given that, two bodies having equal masses are moving with uniform speed of v and 2v, respectively. The kinetic energy of a body is given by :

For first body,

..........(1)

For second body,

..........(2)

From equation (1) and (2) :

So, the ratio of their kinetic energy is 1:4. Hence, this is the required solution.
