Question
During what time interval is the object in uniform motion? What is the velocity for the above question? During what time interval is the object accelerating? What is the acceleration? What is the object doing between t = 0 and t = 7 sec? What is the acceleration for the same interval? What is the object doing between t = 7 sec and t = 18 sec? What is the acceleration? What is the object doing between t = 18 sec and t = 26 sec? What is the acceleration? Describe a scenario where the above motion could occur.Explanation / Answer
8)
the object is in uniform motion , when the veclocity of object is constant ,
hence , the object is in the uniform motion for time t = 0 to 8.5 s
------------
the velocity for the above question is 19.5 m/s
-----
the time interval in which the object is accelerating is when the object is changing.
the time interval is t = 8.5 s to 25 s
---
acceleration = change in velocity/time
acceleration = (5 - 19.5)/(25 - 8.5)
acceleration = -0.88 m/s^2
the acceleration of the object is -0.88 m/s^2
