A force of 60 N imparts an acceleration of 0.8 m / s2 to the body, what force will impart an acceleration of 2.4 m / s 2 to this body?

According to Newton’s second law:
F1 = m * a1, where Fn is the force imparting the acceleration a1 to the body (F1 = 60 N), m is the body weight (kg), and is the acceleration of the body (a = 0.8 m / s²).
Let’s express and calculate the body weight:
m = F / a = 60 / 0.8 = 75 kg.
Let us calculate the force that will impart the acceleration a2 to the same body (a2 = 2.4 m / s²):
F2 = m * a2 = 75 * 2.4 = 180 N.
Answer: To impart an acceleration of 2.4 m / s² to a body, a force equal to 180 N.
