Under the action of a certain force, a body weighing 60 kg moves with an acceleration of 0.4 m / s2.

Under the action of a certain force, a body weighing 60 kg moves with an acceleration of 0.4 m / s2. With what acceleration under the action of this force will a body with a mass of 80 kg move? Define this power.

Task data: m1 (initial body mass) = 60 kg; a1 (acceleration of the original body) = 0.4 m / s2; m2 (mass of the second body) = 80 kg.
1) We define the force acting on the two bodies under consideration: F = m1 * a1 = 60 * 0.4 = 24 N.
2) Determine the acceleration of the second body: a2 = F / m2 = 24/80 = 0.3 m / s2.
Answer: A body weighing 80 kg will move with an acceleration of 0.3 m / s2; the effective force is 24 N.
