2. A 10.0 kg object moving to the right with a speed of 4.0 m/s collides and sticks to a 4.0 kg object moving to the left with a speed of 4.0 m/s. How much energy is lost as heat during the collision?

m1•v1 – m2•v2 = (m1+m2) •u

u = {m1•v1 – m2•v2}/(m1+m2)=

=10•4 - 4•4 /10+4 =1.71 m/s.

m1•v1²/2 + m2•v2²/2-(m1+m2)u²/2 =91.43 J.
