You throw a rock straight up into the air. Ignoring air resistance, is the magnitude of the rock's acceleration greater than
g, equal to
g, less than
gor zero at each of the following moments? At each moment, what is the sign of the acceleration (positive or negative?) Answer both questions for each part below (a) ( 2 points) Immediately after being released from your hand. Magnitude:
a=ga>gaa=ga>g??a=g?a>9aa=g?a>g?a=ga>g??a a=g a>g
Sign: a pasitive ? a is zero ? a negativea a=g ? a>g
Sign: a positive a is zero ? a negative
(e) (2 points) Immediately before returning to your hand.
Magnitude: a a=g a>g
Sign: a pasitive ? a is zero ? a negativea ? a=g ? a>9
Sign: a positive a is zero a negative
(d) (2 points) Half way between the highest point and the point where you released it (on the way down).
Magnitude: a a=g ? a>g
Sign: a positive a is zero ? a negative
(e) (2 points) Immediately before returning to your hand.
Magnitude: a a=g a>g
Sign: a pasitive ? a is zero ? a negativea a=g a>g
Sign: a positive a is zero ? a negative
(c) (2 points) Half way between the highest point and the point where you released it (on the way up).
Magnitude: a ? a=g ? a>9
Sign: a positive a is zero a negative
(d) (2 points) Half way between the highest point and the point where you released it (on the way down).
Magnitude: a a=g ? a>g
Sign: a positive a is zero ? a negative
(e) (2 points) Immediately before returning to your hand.
Magnitude: a a=g a>g
Sign: a pasitive ? a is zero ? a negativea a=g a>g
Sign: a positive a is zero a negative
(b) ( 2 points) At the highest point of the motion.
Magnitude: a a=g a>g
Sign: a positive a is zero ? a negative
(c) (2 points) Half way between the highest point and the point where you released it (on the way up).
Magnitude: a ? a=g ? a>9
Sign: a positive a is zero a negative
(d) (2 points) Half way between the highest point and the point where you released it (on the way down).
Magnitude: a a=g ? a>g
Sign: a positive a is zero ? a negative
(e) (2 points) Immediately before returning to your hand.
Magnitude: a a=g a>g
Sign: a pasitive ? a is zero ? a negative
