Determine the value of the force acting on a body weighing 4.5 kg, if as a result it acquired an acceleration

Determine the value of the force acting on a body weighing 4.5 kg, if as a result it acquired an acceleration of 1.2 m / s2. What force will impart an acceleration of 2.0 m / s2 to the specified body.

According to Newton’s second law, the force acting on the body is:
F = ma, where m is the body mass (m = 4.5 kg), and is the body’s acceleration (m / s ^ 2).
Let’s calculate the value of the acting force at an acceleration of 1.2 m / s ^ 2:
F = m * a = 4.5 * 1.2 = 5.4 N.
Let’s calculate the value of the acting force at an acceleration of 2 m / s ^ 2:
F = m * a = 4.5 * 2 = 9 N.
Answer: The value of the first acting force is 5.4 N, the value of the second acting force is 9 N.
