a 1.2 x10 3 kilogram automobile in motion strikes

A 1.2 x 10^3 kilogram automobile in motion strikes a 1.0 x 10^-4 kilogram insect. As a result, the insect is accelerated at a rate of 1.0 x 10^2 m/s^2. What is the magnitude of the force the insect exerts on the car?
A) 1.0 x 10^-2 N
B) 1.2 x 10^-2 NC) 1.0 x 10^1 N
D) 1.2 x 10^3N
answer : orce on insect = (-) force on car ..
For the insect ..
F = m x a .. 1.0^-4 kg x 1.0^2 m/s² .. .. F = 1.0^-2 N .. .. ►Ans.(A)
