A weight of 30 kg is lifted out of the water using a rope. The forces act on the load: gravity 300 N, tractive force 253N, Archimedean force 100 N and resistance force 50 N. Calculated the acceleration of the load.
Given:
m = 30kg
Ftych = 300N
Fthrow = 253N
FA = 100H
Fcopr = 50N
Decision:
a = F / m
F = Ftyag + FА-Ftyazh-Fsopr
F = 253H + 100H-300H-50H = 3H
a = 3H / 30kg = 0.1 m / s ^ 2
Answer: a = 0.1 m / s ^ 2
