Question

Compare the kinetic energies of 2 objects of masses 10 kg and 50 kg respectively but having same momentum

Answer 1

relation between kinetic energy and momentum ----------

K.E = P^2/2m

if P = constant then kinetic energy inversely proportional to mass of it .

so,

K.E of small object / K.E of big object = 50/10 = 5/1

Answer 2

K.E of small object / K.E of big object = 50/10 = 5/1
