A 5 kg mass moving with a velocity of 10 m/s collides with a 10 kg mass moving with a velocity of 4 m/s in the same direction. Calculate the final velocity of the 10 kg mass assuming an elastic collis

Let's complete the previous question first.

e) A 5 kg mass moving with a velocity of 10 m/s collides with 10 kg mass moving with a velocity of 4 m/s in the same direction along the same line.

i) Calculate the velocity of the 10 kg mass.

Assuming an elastic collision, we use the conservation of momentum and the relative velocity equation.

Given:
Mass 1: $m_1 = 5 \text{ kg}$, $u_1 = 10 \text{ m/s}$
Mass 2: $m_2 = 10 \text{ kg}$, $u_2 = 4 \text{ m/s
