Homework Statement
Two elastic balls, one with mass m = 50 g and the other with mass M = 3m experience a head-on elastic collision after initially traveling in opposite directions at the same speed v = 15 m/s.
Use the conservation of momentum strategy to obtain symbolic expressions and numerical values
for the velocities of the two balls after the collision. (One of the answers is 3E1.)
Homework Equations
Mi1Vi1+Mi2Vi2=Mf1Vf1+Mf2Vf2
The Attempt at a Solution
Well I know that the initial Velocities are going to be the same so
M1+M2(Vi)=M1Vf1+M2Vf2
Would be correct
I'm not sure how you would solve this problem because you are looking for 2 unknowns?
Thanks for any help
