Question

A ball is thrown vertically upward.

Answer 1

Answer:

a. Positive and decreasing

b. 0

c. -9.81 m/s2

d. -9.81 m/s2

e. -9.81 m/s2

Explanation:

a. Since there's a constant gravitational acceleration acting downward, an upward velocity would decrease over time, until it reaches 0 at it's maximum altitude.

b. It's 0 at maximum altitude as it's no longer progressing upward. Otherwise it wouldn't be a maximum altitude.

c. d. and e. Doesn't matter where the ball is, it'd be always subjected to a constant gravitational acceleration, which is 9.81 m/s2/
