$$Mommentum\ P = 45\ kg$$ $$Velosity\ v=32\ m/s $$
$$m=791.016\ Kg$$
$$m = \dfrac{2KE}{v^2}$$ Where: PEg or PE = gravitational potential energy m = mass of an object g = acceleration due to gravity h = height of the object
$$Momentum\ P = 12\ km.m/s$$ $$mass\ m=6\ kg $$
$$v=2\ m/s$$
$$v = \dfrac{p}{m}$$ Where: KE = kinetic energy m = mass of a body v = velocity of a body
