Answer:
During
transportation, the glass wares may break if they collide with each in the
event of jerks. When they are wrapped in straw, the force of jerk is transmitted
to them through the pieces of straw in a longer period of time.
Thus, the change in momentum of the glass wares takes place in a longer
period of time. Therefore, a very small force is experienced by them in the
event to jerks and hence they do not break. (2+1)
