A body with a mass of 5 kg, under the action of some force, changed its speed from 5 m / s

A body with a mass of 5 kg, under the action of some force, changed its speed from 5 m / s to 10 m / s in 5 s. Find the meaning of this power.

Initial data: m (body weight) = 5 kg; V1 (body speed before the force is applied to it) = 5 m / s; V2 (speed of the body after exposure to force) = 10 m / s; t (time of action of the force on the body) = 5 s.

1) Determine the acceleration with which the body began to move.

V2 = V1 + a * t and a = (V2 – V1) / t = (10 – 5) / 5 = 1 m / s ^ 2.

2) Let’s calculate the force that acted on the body: F = m * a = 5 * 1 = 5 N.

Answer: The value of the force that acted on the body is 5 N.
