Se ha calculado que una fuerza resultante de 60 N producira una aceleracion de 10 m/s2 en una carretera ¿Que fuerza se requiere para producir en ella una aceleracion de solo 2 m/s2?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
