Question

Two lumps of clay having equal masses and speeds, but traveling in opposite directions, collide and stick together. Part A Which of the following statements about this system of lumps must be true?

Answer 1

Step-by-step explanation:

mass of clay = m

velocity is u

By use of conservation of momentum

m x u - m x u = (m + m) x v

v = 0

So, they stick together and comes to rest.
