One of the missiles of the Katyusha installation during the Great Patriotic War had a mass of 42.5 kg and was launched with a reactive force of 19.6 kN. What kind of acceleration did he get at the same time?
m = 42.5 kg.
F = 19.6 kN = 19600 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 = 19600 N / 42.5 kg = 461.1 m / s ^ 2.
Answer: the projectile received an acceleration of a = 461.1 m / s ^ 2.
