Question

Two bodies of mass 1kg and 4kg have equal kinetic energy. The ratio of their momentum is

Answer 1

we know kinetic energy = 2 half MV square and if we expand this equation we get half sorry one by 2 m into mm square b square is actually we are multiplying denominator and numerator with M Vinu m square b square is equals to p square where p is the momentum so kinetic energy = 2 p square by 2 m so by this you can relate this equation and you can find the answer of this question
