QUESTION:
12-22. The position of a particle on a straight line is given by.s' = (r3 -9r + 15/) ft, where t is in seconds. Determine the position of the particle when / = 6 s and the total distance it travels during the 6-s time interval. Hint: Plot the path to determine the total distance traveled.
ANSWER:Step 1 of 12
The velocity of the particle can be written as:
Where is the change in position with respect to time,
is given as .
Therefore:
