I will, thank you for checking my work. Have a wonderful weekend.

So, I got Velocity for 0.19 kg cart: 0 = (0.29kg)(1.1m/s) + (0.19)v2f v2f = −1.6789 m/s Kinetic energy: 0.29 kg KE1f = (1/2)(0.29kg)(1.1m/s)2 = 0.17545 J 0.19 kg KE2f = (1/2)(0.19kg)(-1.6789m/s)2 = 0.26781 J KEf = 0.44326 J ΔKE = 0.44326 J - 0 J = 0.44326 J Conservation of Energy: KEi + PEi...

Is this the correct formula to use, if not what is. I really just don't know where to start. I really just need to know where and how to start.
