What force is needed to give a 0.25-kg arrow an acceleration of 196 m/s2?

The force needed is 49 newtons.

Explanation:

Newton's second law can be used to determine the force of the arrow:

 (1)

Where m is the mass of the arrow and a is its acceleration

So the values given can be replaced in equation 1.

But

Therefore, the force needed is 49 newtons.

a person with a mass of 106kg has a weight of 1060n

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
