Question

Derive the mathematical formula of conservation of moment 4m?​

Answer 1

hey mate here's ur ans ^_^

According to the law of conservation of momentum, total momentum must be conserved. The final momentum of the first object is equal to 8 kg * 4 m/s = 32 Ns . To ensure no losses, the second object must have momentum equal to 80 Ns - 32 Ns = 48 Ns , so its speed is equal to 48 Ns / 4 kg = 12 m/s .

hope it helpz

(mark as brainlist if uh want )

Answer 2

Calculate the momentum of the system before the collision. In this case, initial momentum is equal to 8 kg * 10 m/s + 4 kg * 0 m/s = 80 Ns . According to the law of conservation of momentum, total momentum must be conserved. The final momentum of the first object is equal to 8 kg * 4 m/s = 32 Ns .
