7. For a constant force, suppose the duration of

impact on an object is doubled.

a. How much is the impulse increased?

b. How much is the resulting change in

momentum increased? (7.2)

a. impulse increases by the square of the force.

b. momentum also increases

Explanation:

As we know, force is defined as the product of mass and acceleration of the object. Impulse is nothing but the impulse of an object moving is defined as the integral of all the forces acting on the object. As we know that force is a vector quantity and hence the impulse. Since impulse is the integral of all the forces. Here, in the question, it is given that the force is doubled then if you integrate then you get a square function. So, the impulse increases by square function.
