The body is moved along a horizontal platform with an acceleration of 2m / s2. what is the thrust force

The body is moved along a horizontal platform with an acceleration of 2m / s2. what is the thrust force if the body weight is 8 kg and the friction coefficient is 0.5?

To find the traction force applied to the body being moved, we project all the forces onto the horizontal axis OX: m * a = Ftyag – Ftr, from where we express: Ftyag = Ftr + m * a = μ * m * g + m * a.

Variables and constants: μ – coefficient of friction (μ = 0.5); m is the mass of the body being moved (m = 8 kg); g – acceleration due to gravity (g ≈ 10 m / s2); a – acquired acceleration (a = 2 m / s2).

Calculation: Ftyag = μ * m * g + m * a = 0.5 * 8 * 10 + 8 * 2 = 56 N.

Answer: The body was moved along a horizontal platform by a pulling force of 56 N.
