Kinetic energy is also conserved.
This is all the work I have done so far.
(62)(2.8) + (76)(1.6) = 62v1 + 76v2
0.5(62)(2.8)^2 + 0.5(76)(1.6)^2 = 0.5(62)(v1)^2 + 0.5(76)(v2)^2
295.2 = 62v1 + 76v2 and 340.32 = (31)(v1)^2 + (38)(v2)^2
v2= (295.2 - 62v1)/76
340.32 = (31)(v1)^2 +...
1. A 62 kg skater traveling at 2.8 m/s accidentally bumps elastically into a 76 kg skater moving at 1.6m/s in the same direction
Find the velocity of each skater after the collision
2. m1v1 + m1v2 = m1v3 + m2v4
3.
