Two trucks that appear to be identical collide on an icy road. One was originally at rest. The trucks stick together and move off at more than half the original speed of the moving truck. What can you conclude about the contents of the two trucks?

Answer 1

The law of conservation of linear momentum for inelastic collision
m1•v = (m1+ m2)•u =(m1+ m2)•(v/2)
Consenquently, m2=m1
