Question

A ball thrown horizontally at 25.0 m/s from the roof of the building that is 40.0 m height. How far from the base of the building will the ball be landing?

Answer #1

Given,

The initial velocity of the ball in a horizontal direction,

The initial velocity of the ball in a vertical direction,

The height of the building, h = 40 m

For the vertical motion of the ball, from the equation of the motion,

where t = time taken by the ball to reach the ground

g = acceleration due to gravity =

For the horizontal motion of the ball,

where x = distance traveled by the ball in the x-direction

Hence the ball will land 71.42 meters away from the building.

A ball thrown horizontally at 12.7 m/s from the roof of a
building lands 20.2 m from the base of the building.
How tall is the building?
Express your answer using three significant figures and include
the appropriate units.

At t0 = 0 s a ball is thrown horizontally from the roof of a
building 9.0 m tall. It lands 9.5 m from the base of the
building.
a. What was the initial speed of the ball? v0 =
b. What was the impact speed of the ball? v1 =
c. At what time did the ball strike the ground? t1 =

A
ball thrown horizontally from the roof of a building 7.50m tall.
the ball lands at 9.75 m away from the base. 1) how much time does
it take for the ball to land? 2) how much is the initial velocity
of the ball?

A ball is thrown horizontally from a 20m high building with a
speed of 7.0 m/s. How far from the base of the building does the
ball hit the ground? Express your answer with two significant
figures.

A ball is thrown horizontally from a 18m -high building with a
speed of 9.0m/s .
How far from the base of the building does the ball hit the
ground?
Please show all work and equations thank you!

1. A ball is thrown horizontally of a cliff. If the initial
speed of the ball is (15.0+A) m/s and the cliff is (25.0+B) m high,
how far from the base of the cliff will the ball land in the water
below? Calculate the answer in meters (m) and rounded to three
significant figures. A=8 B= 68
2. A water balloon is launched at a speed of (15.0+A) m/s and an
angle of 36 degrees above the horizontal. The water...

A ball is thrown horizontally from the top of a 53.0-m building

resistance. (Assume the ball is thrown in the +x direction
and upward to be in the +y direction.)
a) How long (in s) is the ball in the air? in s
b) What must have been the initial horizontal component of the
velocity (in m/s)? (Indicate the direction with the sign of your
answer.) in m/s...

A ball is thrown horizontally from the top of a 70.0-m building
and lands 90.0 m from the base of the building. Ignore air
resistance. What is the velocity just before it hits the ground? In
meters per second

A ball is thrown horizontally from the top of a 70.0-m building
