a) what is the mass of the second cart?

b)What is its speed after impact?

c)What is the speed of the two-cart center of mass?

I know that in an elastic collsion momentum and energy is conserved. What would be the equation i would use for this problem? I can't figure out the equations for a) and b) but I think for

c) would I use V= (m_1* v_1 + m_2 *v_2)/(m1+m2)

**Anonymous**, Tuesday, October 21, 2014 at 2:54pmThe equation for the first part is

V_1Final = [(m_1-m_2)/(m_1+m_2)]*V_1Origional

I used conservation of momentum for the second part.
