Answer 2

Answer:

The impulse experienced by Annie's car will be 10⁵Kgms⁻¹.

Explanation:

Given that Mass of Annie's car, $m=2000Kg$

Initial velocity of the car, $v_{i}=50ms^{-1}$

Final velocity of the car, $v_{f}=100ms^{-1}$

The qualify effect of the force on a body within time to change the momentum of the body is known as impulse.

Impulse is given by:

$J=m(v_{f}-v_{i})$

$J=(2000Kg)(100-50)ms^{-1}$

$J=(2000)(50)kgms^{-1}$

$J=10^{5}Kgms^{-1}$

Therefore the impulse experienced by the car is equal to $10^{5}Kgms^{-1}$.
