In the vector addition lab, the following data was collected for determining the displacement from the door of the physics classroom to another location in the building: 2.0 m, west

22.0 m, south

25.0 m, east

9.0 m, north

4.0 m, west

the direction of the resultant displacement is closes to __ degrees.(use the counter-clockwise from east convention) enter a numerical answer

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?

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).

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
