Akhtar, Kiran and Rahul were riding in a motorocar 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
explanation said that both the motorcar and the insect experienced the same force and a
change in their momentum. Comment on these suggestions.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
