With what acceleration will a body with a mass of 10 kg move if forces of 20 and 30 N act on it in opposite directions?

According to Newton’s second law:

F = m * a, where F is the resultant force (N), m is the mass of the body (m = 10 kg), and is the acceleration of the body.

Since F1 and F2 are directed in opposite directions, the resultant force is equal to:

F = F1 – F2, where F1 = 30 N, F2 = 20 N.

F = F1 – F2 = 30 – 20 = 10 N.

Let’s express and calculate the acceleration of the body:

a = F / m = 10/10 = 1 m / s².

Answer: The body will move with an acceleration of 1 m / s².
