Question

Consider a rock that is thrown off a bridge of height 82 m at an
angle *θ* = 22° with respect to the horizontal as shown in
the figure below. If the initial speed the rock is thrown is 13
m/s, find the following quantities.

(a) The time it takes the rock to reach its maximum
height.

s

(b) The maximum height reached by the rock.

m

(c) The time at which the rock lands.

s

(d) The place where the rock lands.

m

(e) The velocity of the rock (magnitude and direction) just before
it lands.

magnitude | m/s |

direction | ° |

Answer #1

Rock thrown off a cliff
You want to know the height of a cliff so you throw a rock off the
edge with an initial speed of 18.5 m/s inclined at an angle 30.3°
above the horizontal. You have a friend that records that it takes
3.4 s for the rock to hit the bottom of the canyon after it is
thrown. For the following questions, call up the positive
y direction and make the positive x direction
horizontal and...

A rock is thrown from the edge of a cliff to the ground 17.0 m
below. The rock has an initial velocity of 20.0 m/s, directed 35.0°
above the horizontal. (a) How long does it take the rock to reach
the ground?
(b) How far from the base of the cliff does the rock strike the
ground?
(c) Find the velocity of the rock just before it strikes the
ground.

A rock is thrown from the edge of a cliff 125m above the ground
with an initial speed of 65.0m/s and at an angle of 37.0 degree
with respect to the horizontal. A). What is the maximum height
above the ground that the rock will reach? B). How long does it
take for the rock to hit the ground? C). How far from the bottom of
the cliff will the rock hit the ground?

A rock is thrown from the top of a building 80 m high, with a
speed of 14 m/s at an angle 25 degrees above the horizontal. When
it hits the ground, what is the magnitude of its velocity (i.e. its
speed).

A man stands on the roof of a 19.0 mm -tall building and throws
a rock with a velocity of magnitude 30.0 m/sm/s at an angle of 42.0
∘∘ above the horizontal. You can ignore air resistance.
Calculate the maximum height above the roof reached by the
rock.
Calculate the magnitude of the velocity of the rock just before
it strikes the ground.
Calculate the horizontal distance from the base of the building
to the point where the rock strikes...

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 3.0 s later.
a) How high is the cliff?
b) What was the maximum height of the ball?
c) What is the ball's impact speed?

Suppose the ball is thrown from the same height as in the
PRACTICE IT problem at an angle of 27.0°below the horizontal. If it
strikes the ground 56.3 m away, find the following. (Hint:
For part (a), use the equation for the x-displacement to
eliminate v0t from the equation for
the y-displacement.) horizontal range (height) = 88.64

(a) the time of flight = _____s
(b) the initial speed = _____ m/s
(c) the speed and angle of the velocity...

An angry bird is thrown from a slingshot in 2.50 m height with
the starting speed of 15.9 m/s. The bird lands on a naughty pig in
3.60 m height and 14 m horizontal distance from the slingshot.
a) calculate the shooting angle i.e. the direction of the
starting speed of the bird. You may use iteration to calculate, or
the equtaion 1/cos2? =
1+tan2?. Is one angle that is possible or mor?
discuss.
b) What is the speed of the...

A boy kicks a rock off a cliff with a speed of 18.2 m/s at an
angle of 54.0° above the horizontal. The rock hits the ground 5.21
s after it was kicked.
How high is the cliff?
What is the speed of the rock right before it hits the
ground?
What is the maximum height of the rock in the air, measured from
the top of the cliff

4. A ball is thrown at 20 m/s at an angle of 7 degrees above the
horizon.
a. How far does it reach if it is thrown from a height of 2
m?
b. What would the horizontal component of the velocity be as the
ball hits the ground?
c. What would the overall speed of the ball be as it hits the
ground?
