Question

two bodies are moving with same kinetic energy and their masses are in the ratio 1 :2. The ratio of their velocities is

Answer 1

1:1
Go by the Formula p=√2mk
k is kinetic energy

Answer 2

it is given that 2 bodies are equal so,
k1 = k2
and
v=?
k1÷k2 = half mv1^2 ÷ half mv2^2
half is cancel by half so we get,
k1÷k2 = mv1^2 ÷2mv^2
and,
k1 is cancel by k2 so we get,
2:1 = v1^2 : v2^2
hence prove
