This seems easy and yet i'm skeptical if these are actually supposed to be difficult.. It asks for a lot. It's seems repetitive..
1. a falling stone takes .30 seconds to travel past a window 2.2m tall. From what height above the top of the window did the stone fall?
2.
(a) Is the object moving in the positive or negative direction?
not moving
negative
positive
(b) Is the object speeding up or slowing down?
neither
speeding up
slowing down
(c) Is the acceleration of the object positive or negative?
no acceleration
positive
negative
***Next, for the time interval from D to E:
(d) Is the object moving in the positive or negative direction?
negative
positive
not moving
(e) Is the object speeding up or slowing down?
speeding up
slowing down
neither
(f) Is the acceleration of the object positive or negative?
negative
no acceleration
positive
Finally, answer these same three questions for the time interval from C to D.
***Is the object moving in the positive or negative direction?
not moving
negative
positive
***Is the object speeding up or slowing down?
speeding up
slowing down
neither
***Is the acceleration of the object positive or negative?
no acceleration
positive
negative

Here is a picture
Nevermind I got it
1. To determine the height from which the stone fell, we can use the formula for free fall motion:
h = (1/2)gt^2
Where:
h is the height above the top of the window
g is the acceleration due to gravity (approximately -9.8 m/s^2)
t is the time it takes the stone to travel past the window (0.30 seconds)
Plugging in the values, we get:
h = (1/2)(-9.8 m/s^2)(0.30 s)^2
h = (1/2)(-9.8 m/s^2)(0.09 s^2)
h = (-4.9 m/s^2)(0.09 s^2)
h = -0.44 m
Since the height can't be negative, we consider the magnitude and the stone fell from a height of 0.44 meters above the top of the window.
2. For the questions related to positive/negative direction, speeding up/slowing down, and positive/negative acceleration, we need more information about the object's motion during the specified time intervals (D to E and C to D).
Please provide the necessary information or any additional context about the object's motion during those time intervals, so I can assist you further.
