Question 1
A ball is thrown straight down off a 4-meter balcony at a speed of 11 m/sec. How many seconds will it take to hit the ground at the base of the balcony?
0.32 sec
omit
Question 2
How
fast
will the ball in
Question #1
be traveling just as it impacts the ground?
14.1 m/sec
omit
Question 3
If the ball in
Question #1
had instead been thrown straight upwards at a speed of 11 m/sec off the 4-meter balcony, how much time would it have taken to strike the ground at the base of the balcony?
2.56 sec
omit
Question 4
How
fast
will the ball in
Question #3
be traveling just as it impacts the ground?
14.1 m/sec
omit
Question 5
How high
above the release point
did the ball in
Question #3
rise during its trajectory?
6.17 meters
omit
Question 6

2.24 seconds
omit
Question 7
A walnut drops from the top branch of a walnut tree and falls a total distance of 18 meters. After one second, it clears all of the tree's foliage. How much additional time passes before it strikes the ground at the base of the tree?
