A solid metal ball is thrown from the top of a building at an
angle of 30° above the horizontal with an initial speed of 13 m/s.
The ball lands on the ground 3.4 s after it is thrown.
A ball is thrown from the top of a building at an angle of
30degrees above the horizontal and with an initial speed of 20m/s.
if the ball is in flight for 4seconds A) how tall is the building?
b)what horizontal distance does the ball travel? c) what maximum
height does the ball reach? d)with what speed and angle of impact
does the ball land?
1) A ball is thrown from the top of a roof at an angle of 20 o
with respect to the vertical. 1 s later a ball is dropped from the
top of the roof
a) If the height of the roof is 20 m, determine the velocity
with which the first ball must be thrown in
order for both balls to land at exactly the same time.
b) Imagine the velocity of the first ball is now known, and...
A stone is thrown from the top of a building at an angle of
-20.0 degrees relative to the horizontal with an initial velocity
of 30.0 m/s. The building is 65.0 m tall. 1. Determine how long the
stone is in the air 2. Determine the speed of the stone right
before it hits the ground. 3. determine the angle of velocity with
respect to the x-axis at impact. 4. Determine where the stone
strikes the ground.
A ball is thrown from a building of height 40.0 m at angle of θ
= 40° (relative to the horizontal). The ball hits the ground 5.0s
later.
(a) Sketch a diagram to illustrate the trajectory of the ball.
(b) Find the horizontal distance d it travels.
(c) When does the ball reach the maximum height?
(d) What is the magnitude of the ball’s velocity just before
striking the ground?
(e) What is the angle (relative to the horizontal) of...
a Ball is thrown upward from the top of a 23.5 m building with a

Part I
A ball is thrown straight up from the top of a building that is
185ft high with an initial velocity of 64ft/s. The height of the
object can be modeled by the equation s(t) =
-16t 2 + 64t + 185.
In two or more complete sentences explain how to determine the
time(s) the ball is higher than the building in interval
notation.
Part II
In two or more complete sentences, describe the
transformation(s) that take place on...
A ball is thrown vertically downward from the top of a
33.0-m-tall building. The ball passes the top of a window that is
10.8 m above the ground 2.00 s after being thrown. What is the
speed of the ball as it passes the top of the window?
A 700 gram ball is thrown from the top of a 25 meter tall
building. The ball is thrown with an initial speed of 10 m/s at an
angle 30 degrees above the horizontal. For our conservation of
energy calculations, we will choose the Ball + Earth as our system
and use the ground as h = 0.
The kinetic energy of the ball when it is thrown
= J.
When the ball reaches its highest point the kinetic energy is...
