Answer:
Pulleys accomplish 2 separate operations throughout the computer controlled additional benefit technologies listed elsewhere here. 
Explanation:
- If indeed the pulley would be connected to that same attachment point, these are named a corrected pendulum or perhaps a change in direction. Its job should be to reverse the trajectory of that same rope pull.  
- Unless the pulley would be connected to that same load, this same pulley seems to be a detachable as well as a mechanical additional benefit.
 
        
             
        
        
        
Answer:
The acceleration is in 2 D as in between east and south. 
Explanation:
mass, m = 50 kg 
acceleration, a = 0.25 m/s^2 horizontal
acceleration of elevator, a' = 1 m/s^2 downwards
When a person on the ground the resultant acceleration of the person with respect to the ground is between east and south direction so the path os parabolic in nature. It graph is shown below: 
 
        
             
        
        
        
Answer:
 12000 miles per hour

Time period = 1 / frequency 
Time period = 1 / 250 th of a second
