Suppose a small box with a mass of 4.00kg is moving at 10.0m/s along a flat horizontal surface immediately before it begins travelling down a slope. The slope is at an angle of 20.0∘, has a length of 8.00m, and the coefficent of kinetic friction between the slope and the box is 0.750. What is the velocity of the box when it reaches the bottom of the slope?

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).
