Elastic collision
$\displaystyle m_1=3kg$
$\displaystyle u_1=10ms^{1}$
$\displaystyle m_2=2kg$
$\displaystyle u_2=0$
The collision is elastic.
Find:
$\displaystyle v_1$ and $\displaystyle v_2$
By using total kinetic energy is conserved, I get 2 sets of answer.
$\displaystyle v_1=10$ , $\displaystyle v_2=0$
$\displaystyle v_1=2$ , $\displaystyle v_2=12$
Which is the correct answer?Or both are acceptable?
