A bar with a mass of m = 500 g begins to move along a horizontal surface, applying a horizontal force to it F = 2 N. With what acceleration does the body move. Friction is neglected.
m = 500 g = 0.5 kg.
F = 2 N.
a – ?
According to Newton’s 2 law, the acceleration of a body a is directly proportional to the force F, which acts on the body, and is inversely proportional to the body’s mass m.
The acceleration of the body a, is determined by the formula: a = F / m.
a = 2 N / 0.5 kn = 4 m / s ^ 2.
Answer: the body moves with an acceleration a = 4 m / s ^ 2.
