collides with the first from behind and sticks to it. The final velocity of the combined blocks is 3.2m/s.What was the mass of the second block?-m2 = m1(v3-v1)/(v2-v3) = 5.m2 = 5.......
A 2.9 kg block slides along a frictionless surface at 1.4 m/s. A second block, sliding at a faster 4.2 m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is 3.2 m/s.What was the mass of the second block?

m2 = m1(v3-v1)/(v2-v3) = 5.22kg

m2 = 5.2kg
