Compute all parts of given question:

Question: The position of an object moving in a straight line is given by x = 5t-t2+9t3, where x is in meters and t in seconds.

Part A: What is the position of the object at t = 1s?

m

Part B: What is the position of the object at t = 2?

m

Part C: What is the position of the object at t = 3?

m

Part D: What is the position of the object at t = 4 s?

m

Part E: What is the object's displacement between t = 0 and t = 4 s?

m

Part F: What is the average velocity for the time interval from t = 2 s to t = 4 s?

m/s

Rework your solution from the starting and check each step carefully. Thanks.
