A 23.9 #kg# mass has a #3i-2jm/s# velocity and a 21.3 #kg# mass has a #3i-10jm/s# velocity. What is the magnitude of the total momentum of the two masses? Physics Momentum and Collisions Momentum and Impulse 1 Answer ali ergin Feb 15, 2018 #"please have a look at the fallowing details."# Explanation: #vec P_1=m_1*vec v_1# #vec P_1=23.9*(3i-2j)=71.7i-47.8j# #vec P_2=m_2*vec v_2# #vec P_2=21.3(3i-10j)=63.9i-213j# #Sigma vec P=vec P_1+vec P_2# #Sigma vec P=71.7i+63.9i+(-47.8j-213j)# #Sigma vec P=135.6i-260.8j" total momentum vector"# #P=sqrt((135.6)^2+(-260.8)^2)" magnitude"# #P=sqrt(18387.36+68016.64)# #P=293.95 kg " "*ms^-1# Answer link Related questions Question #ce067 Question #13b3d If the velocity of an object doubles, does its momentum double?
