Question

A consequence of more mass having more inertia is that ______________ is required to bring the helicopter to the same speed as the bullet.A. less forceB. more forceC. equal force

Answer 1

option (B)

Step-by-step explanation:

Momentum is the measure of motion of the body.

Momentum of a boy is equal to the product of mass of the body and its velocity.

As helicopter has more mass than a bullet so it has more momentum than the bullet.

According to the Newton's second law, force is directly proportional to the rate of change of momentum. So, more change in momentum means more force is required.

Thus, more force is required to bring the helicopter to the same speed as the bullet.

Answer 2

A consequence of more mass having more inertia is that more force is required to bring the helicopter to the same speed as the bullet

Step-by-step explanation:

The second law of motion gives the measure of force acting on the object. It is given by the product of mass and its acceleration. It is given by :

F = m × a

Inertia of an object is the measure of its mass. It is clear form second law that the force is directly proportional to the mass of an object.

In this case, the case of bullet and helicopter is given. We know that the bullet has less mass as compared to helicopter.

So, a consequence of more mass having more inertia is that more force is required to bring the helicopter to the same speed as the bullet
