The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

    \n
  1. Hypothesis<\/strong>:\n
      \n
    • Initially, before the collision, Ball 1 has momentum P=m\u00d7vP = m \\times vP=m\u00d7v. With the given mass and velocity for Ball 1, the momentum is: P1=1.5\u2009kg\u00d71\u2009m\/s=1.5\u2009kg.m\/sP_1 = 1.5 \\, \\text{kg} \\times 1 \\, \\text{m\/s} = 1.5 \\, \\text{kg.m\/s}P1\u200b=1.5kg\u00d71m\/s=1.5kg.m\/s For Ball 2, its initial momentum is: P2=1.5\u2009kg\u00d70.50\u2009m\/s=0.75\u2009kg.m\/sP_2 = 1.5 \\, \\text{kg} \\times 0.50 \\, \\text{m\/s} = 0.75 \\, \\text{kg.m\/s}P2\u200b=1.5kg\u00d70.50m\/s=0.75kg.m\/s Therefore, the Net Momentum<\/strong> before the collision is the sum of the momenta of both balls: Net\u00a0Momentum=1.5\u2009kg.m\/s+0.75\u2009kg.m\/s=2.25\u2009kg.m\/s\\text{Net Momentum} = 1.5 \\, \\text{kg.m\/s} + 0.75 \\, \\text{kg.m\/s} = 2.25 \\, \\text{kg.m\/s}Net\u00a0Momentum=1.5kg.m\/s+0.75kg.m\/s=2.25kg.m\/s<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Actual Results (after the collision)<\/strong>:\n
        \n
      • After the collision, you’ll need to observe the new velocities of Ball 1 and Ball 2 from the simulation. Let\u2019s assume Ball 1’s velocity changes to 0.5\u2009m\/s0.5 \\, \\text{m\/s}0.5m\/s and Ball 2’s changes to 1.0\u2009m\/s1.0 \\, \\text{m\/s}1.0m\/s.<\/li>\n\n\n\n
      • The new momenta will be: P1\u2032=1.5\u2009kg\u00d70.5\u2009m\/s=0.75\u2009kg.m\/sP_1′ = 1.5 \\, \\text{kg} \\times 0.5 \\, \\text{m\/s} = 0.75 \\, \\text{kg.m\/s}P1\u2032\u200b=1.5kg\u00d70.5m\/s=0.75kg.m\/s P2\u2032=1.5\u2009kg\u00d71.0\u2009m\/s=1.5\u2009kg.m\/sP_2′ = 1.5 \\, \\text{kg} \\times 1.0 \\, \\text{m\/s} = 1.5 \\, \\text{kg.m\/s}P2\u2032\u200b=1.5kg\u00d71.0m\/s=1.5kg.m\/s So the Net Momentum<\/strong> after the collision is: Net\u00a0Momentum=0.75\u2009kg.m\/s+1.5\u2009kg.m\/s=2.25\u2009kg.m\/s\\text{Net Momentum} = 0.75 \\, \\text{kg.m\/s} + 1.5 \\, \\text{kg.m\/s} = 2.25 \\, \\text{kg.m\/s}Net\u00a0Momentum=0.75kg.m\/s+1.5kg.m\/s=2.25kg.m\/s This is the same as the net momentum before the collision.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Conclusion<\/strong>:
        In an elastic collision, momentum is conserved, which means that the total net momentum before and after the collision remains the same. In this case, the total net momentum is 2.25 kg.m\/s both before and after the collision.<\/li>\n<\/ol>\n\n\n\n

        This experiment demonstrates the principle of conservation of momentum in elastic collisions, where there is no loss of total momentum even though individual momenta of the objects may change.<\/p>\n\n\n\n
