Question

actor Kiran and Rahul were Riding in a motor car that was moving with a high velocity on Expressway when an insect it the wind shield and got stuck on the windscreen actor and Kiran started found rain over the situation period suggested that the insects offer a greater challenge when the velocity of the insect was much more than that of the motor car after said that since the motor car was moving with a large velocity it exerted a larger force on the insect and as a result the insect bite Rahul while putting and it really new explanation said that both the motor car and insulin side experienced the same force and a change in their Momentum comment on this suggestion

Answer 1

I agree with Rahul.This is because due to the law of conservation of momentum, during a collision, momentum of the system is conserved.Both the bodies suffer the same momentum change.However, the insect having smaller mass will suffer greater change in velocity.The motor car having much larger mass does not suffer any noticeable change in velocity.

Answer 2

☆$\red {HELLO\:DEAR}$☆

According to the law of conservation of momentum:

Momentum of the car and insect system before collision = Momentum of the car and insect system after collision

Hence, the change in momentum of the car and insect system is zero.

The insect gets stuck on the windscreen. This means that the direction of the insect is reversed. As a result, the velocity of the insect changes to a great amount. On the other hand, the car continues moving with a constant velocity. Hence, Kiran’s suggestion that the insect suffers a greater change in momentum as compared to the car is correct. The momentum of the insect after collision becomes very high because the car is moving at a high speed. Therefore, the momentum gained by the insect is equal to the momentum lost by the car.

Akhtar made a correct conclusion because the mass of the car is very large as compared to the mass of the insect. Rahul equal to the momentum after the collision.
