9. Two people are fighting over a Playstation 5 . One ( 100 mathrm{~kg} ) customer eventually winds up at a speed of ( 10 mathrm{~m} / mathrm{s} ) on another ( 125 mathrm{~kg} ) customer. What was the recoil velocity of the ( 125 mathrm{~kg} ) customer? ( (8 mathrm{~m} / mathrm{s}) )

Question

Accepted Answer

Step:1 ：( m_1 = 100 mathrm{~kg} )Step:2 ：( m_2 = 125 mathrm{~kg} )Step:3 ：( v_1 = 10 mathrm{~m} / mathrm{s} )Step:4 ：( m_1 v_1 = m_2 v_2 )Step:5 ：( v_2 = frac{m_1 v_1}{m_2} )Step:6 ：( v_2 = frac{100 times 10}{125} = 8 mathrm{~m} / mathrm{s} )

Answer

Step: 1 ：( m_1 = 100 mathrm{~kg} )Step: 2 ：( m_2 = 125 mathrm{~kg} )Step: 3 ：( v_1 = 10 mathrm{~m} / mathrm{s} )Step: 4 ：( m_1 v_1 = m_2 v_2 )Step: 5 ：( v_2 = frac{m_1 v_1}{m_2} )Step: 6 ：( v_2 = frac{100 times 10}{125} = 8 mathrm{~m} / mathrm{s} )

9. Two people are fighting over a Playstation 5 . One $100 kg$ customer eventually winds up at a speed of $10 m / s$ on another $125 kg$ customer. What was the recoil velocity of the $125 kg$ customer? $(8 m / s)$
