    Homework: conservation of momentum

    The two equations are M*v1 + (m2-M)*v2 = 0 and (m1-M)*v1 + M*v2 = m1*u1 ? I hope so. At least they give correct answer, I use them.:smile: Thank you Michael

    Homework: conservation of momentum

    thank you, but ... I wrote two equations v1*m1+v2*m2 = u1*m1 and (m1*v1^2)/2 + (m2*v2^2)/2 = (m1*u1^2)/2 the result is not M dependent ? when I solve the equations I get wrong answers. (correct is v1=9m/s and v2=-1m/s) Or when and why should M in kinetic energy equation be...

    Homework: conservation of momentum

    Sorry my English is very poor. one boat is going East and the other West, when they meet an object of mass 50kg is handed over from boat1 to boat2 and at the same time other object of same mass is handed from boat2 to boat1Thank you Michael

    Homework: conservation of momentum

    Hi, could you please help me with following: ---------- two boats traveling in opposite direction with speed v1 and v2 when they are passing by they interchange a parcel of same mass M=50kg as a result second boat stops and first boat continue traveling in same direction with speed...
