Question

Two object have equal masses if their velocities have the ratio 2:3 find the ratio of their kinetic energies

Answer 1

Explanation:

m1=m2

v1:v2= 2:3

therefore

v1/v2= 2/3

m1/m2=1:1

k1=1/2m1×2v1

k2= 1/2m2×3v2

=> k1 = 1/2m1×2v1

---- ---------------

k2 1/2m2×3v2

k1:k2::2:3

I don't know if its wrong or right

But i hope this shall help you

Thanks
