A ball is thrown straight up with an initial speed of 19 m/s.
The ball was released 6.3 m above the ground, but when it returns
back down, it falls into a hole d m deep. If the ball’s speed is
35.7 m/s at the bottom of the hole, how deep is the hole (in
m)?
A ball is thrown toward a cliff of height h with a speed of 30
m/s and an angle of 60° above horizontal. It lands on the edge of
the cliff 4.0 s later.
How high is the cliff?
What was the maximum height of the ball?
What is the ball’s impact speed?
a ball is thrown up onto a roof, landing 3.60 s later at height
h = 25.0 m above the release level. The ball's path just
before landing is angled at ? = 64.0?with the roof.
(a) Find the horizontal distance d it
travels. (Hint: One way is to reverse the motion, as if it
is on a video.) What are the (b) magnitude and
(c) angle (relative to the horizontal) of the
ball's initial velocity?
A blue ball is thrown upward with an initial speed of 24.3 m/s,
from a height of 0.9 meters above the ground. 3 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 8.2 m/s from a height of 33.3 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.

A blue ball is thrown upward with an initial speed of 22.2 m/s,
from a height of 0.5 meters above the ground. 2.7 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 10.7 m/s from a height of 26.9 meters above the ground.

A red ball is thrown down with an initial speed of 1.4 m/s from
a height of 29 meters above the ground. Then, 0.6 seconds after the
red ball is thrown, a blue ball is thrown upward with an initial
speed of 25.6 m/s, from a height of 1 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.

A red ball is thrown down with an initial speed of 1.3 m/s from
a height of 27 meters above the ground. Then, 0.5 seconds after the
red ball is thrown, a blue ball is thrown upward with an initial
speed of 23.9 m/s, from a height of 0.7 meters above the ground.

A ball thrown straight up into the air is found to be moving at
7.24 m/s after falling 2.27 m below its release point. Find the
ball's initial speed. Thank you.
