Under the action of a force of 150 N, the body moves rectilinearly so that its coordinate changes according to the law x = 100 + 5t + 0.5t ^ 2. What is body weight?
From the coordinate equation it follows that the motion is uniformly accelerated, the acceleration is 1m / s ^ 2
According to Newton’s second law:
a = F / m
m = F / a = 150/1 = 150kg
