Answer:
The speed of the white puck immediately after the collision is 2.6 m/s.
Explanation:
Given that,
Two pucks are equal masses.
Speed of black puck = 1.5 m/s
According to given figure,
We need to calculate the speed of the white puck immediately after the collision
Using law of conservation of momentum

Put the value into the formula according to figure




Hence, The speed of the white puck immediately after the collision is 2.6 m/s.

Answer:
Inelastic collisions actually do conserve energy, but the loss of energy to heat and mechanical vibration is hard to calculate so the math equating energy before and energy after is hard to balance.
The correct answer is #4. They have the same number of protons but a different number of neutrons.
