if the mass of the person's head is 4.8 kg , what is the magnitude of the force? express your answer using appropriate units.

Respuesta :

The calculated magnitude of force is 47.04 N. Second Law of Motion by Newton (Force) An object's acceleration is determined by its mass and the force being applied.

All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass. The acceleration that gravity gives to objects falling freely serves as a gauge of its strength. The acceleration of gravity at Earth's surface is approximately 9.8 meters (32 feet) per second every second. The magnitudes of the object's weight and the normal force are equal when the object is resting on a horizontal surface and there are no other vertically acting forces; that is, Therefore, the normal force in this case is 26 N, which is much greater than the box's weight.

F=ma

F= 4.8 * 9.8

=47.04 N
