Class 9th | Force and laws of motion | Exercise question no. 16.
Akhtar, Kiran and Rahul were riding in a motorcar that
was moving with a high velocity on an expressway when an
insect hit the windshield and got stuck on the windscreen.
Akhtar and Kiran started pondering over the situation. Kiran
suggested that the insect suffered a greater change in
momentum as compared to the change in momentum of the
motorcar (because the change in the velocity of the insect
was much more than that of the motorcar). Akhtar said
that since the motorcar was moving with a larger velocity,
it exerted a larger force on the insect. And as a result the
insect died. Rahul while putting an entirely new explanationsaid that both the motorcar and the insect experienced the
same force and a change in their momentum. Comment on
these suggestions.
