With what acceleration will a body with a mass of 400 g move under the action of a single force of 8 N?
| September 19, 2021 | education
m = 400 g = 0.4 kg.
F = 8 N.
a -?
According to 2 Newton’s law, the acceleration of a body a is directly proportional to the force F, which acts on the body, and inversely proportional to the mass of the body m: a = F / m.
a = 8 N / 0.4 kg = 20 m / s ^ 2.
Answer: the body under the action of force moves with acceleration a = 20 m / s ^ 2.
