Cars motion in kg & m/s?

Marcellus Exler: (m1) = 100kg(m2) = 100kg(Vi1) = 6.8m/s(Vf1) = 5m/s(Vf2) = -30m/s(Vi2) = ?(Variables: Mass car 1, mass car 2, velocity initial car 1, velocity final car 1, velocity final car 2, velocity initial car 2, respectively)(m1)*(Vi1) + (m2)*(Vi2) = (m1)*(Vf1) + (m2)*(Vf2)Therefore, (Vi2) = ((m1)*(Vf1) + (m2)*(Vf2) - (m1)*(Vi1)) / (m2)= (100*5 + 100*(-30) - 100*6.8) / 100= -31.8m/sHope this helps ;)...Show more
