Awoman of mass 57 kg jumps off the bow of a 42 kg canoe that is intially at rest. if her velocity is 1.5 m/s to the right, what is the velocity of the canoe after she jumps?

Here we will use the momentum conservation

Since there is no external force on this system so momentum of woman + canoe system will always remains conserved

So here initial momentum of the system is zero as they are at rest so final momentum will always be zero

so the canoe will go back with speed 2.03 m/s

radiation

explanation:

heat is transmitted by radiation
