Question

Use it to determine the overall placement (in m) of the object during the 20.0 seconds of motion. Enter the appropriate + or - sign.

A. +80 m
B. -80 m
C. +160 m
D. -160 m

Answer 1

The overall placement of the object during 20 seconds of motion is +80 m.

Step-by-step explanation:

The student is asking for the overall placement of an object during 20 seconds of motion. To determine this, we need to use the given information and equations. First, we can discard the negative value for time as it is unreasonable. Then, we divide the net displacement of 16,325 m by the total time of 70 s, which gives us a velocity of approximately 233 m/s. Since the velocity is positive, the overall placement of the object would be in the positive direction, so the answer is option A: +80 m.
