Question

two bodies of equal masses move with uniform velocity v1 and v2 respectively. If the ratio of their kinetic energy is 16:25,then found the ratio of v1 and v2. please help​

Answer 1

Explanation:

We know

K.E. = 1/2 mv^2

Let,Kinetic energy of first body be K1 and that of the second body be K2.

Let each has mass m.

Given

K1/K2= 16/25

Now,

K1=1/2 m v1^2

v1^2= 2K1/m

and,

K2=1/2 m v2^2

v2^2 = 2K2/m

Therefore,

(v1/v2)^2 = K1/K2=16/25

v1/v2=4/5.

Hope it will help you.
