A body weighing 200 g moves with acceleration, the modulus of which is 4.0 m / s2.

A body weighing 200 g moves with acceleration, the modulus of which is 4.0 m / s2. Determine the modulus of the resultant forces acting on the body.

The resulting force will produce an action on the body that is equal to the action of all simultaneously acting forces. Therefore, the resultant force is equal to:
R = ׀ F ׀ = m * a, where m is the mass of the body (m = 200 g = 0.2 kg), a is the acceleration of the body (a = 4 m / s ^ 2).
Let’s calculate the resultant force:
R = m * a = 0.2 * 4 = 0.8 N.
Answer: The resultant force is 0.8 N.
