A 98 kilogram man is accelerating forward at a rate of 1.2 m/s2. What is the unbalanced force necessary to produce the movement?

Respuesta :

F = ma 

F = 98(1.2)

F = 117.6 N

This is Option D in you listed choices.  


Answer : The unbalanced force necessary to produce the movement is, 117.6 N

Solution :

Force : It is defined as the force is equal to the product of the mass of an object and the acceleration of an object.

Formula used :

[tex]F=m\times a[/tex]

where,

F = force

m = mass = 98 Kg

a = acceleration = [tex]1.2m/s^2[/tex]

Now put all the given values in the above formula, we get the unbalanced force necessary to produce the movement.

[tex]F=(98Kg)\times (1.2m/s^2)=117.6\text{ Kg }m/s^2=117.6N[/tex]

Therefore, the unbalanced force necessary to produce the movement is, 117.6 N
