Question

A ball is thrown horizontally from the top of a 68 m building and lands 110 m from the base of the building. Ignore air resistance.

a. What is the vertical component of the velocity just before the ball hits the ground?

c. What is the angle of the ball just before it hits the ground ( in degrees below x-axsis)?

Answer #1

According to the equations of kinematics in 2D motion we solve this qn

Hence the answer is a)vertical velocity is 0.0028m/s

b) angle at which ball hits below x axis which is theta is 67.96 degree

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 57.5-m building
and lands 122.3 m from the base of the building. Ignore air
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?
(b)
What must have been the initial horizontal component of the
velocity (in m/s)? (Indicate the direction with the sign of your
answer.)
(c)
What is the...

resistance. What is the velocity just before it hits the
ground?
Just give the magnitude in meters/second here.

A ball is thrown horizontally from the top of a 53.0-m building
and lands 119.3 m from the base of the building. Ignore air
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 building hits
the ground 0.25 s later, Ignore air resistance. If it had been
thrown with twice the speed in the same direction, it would have
hit the ground in:
A) 0.40 s
B) 0.50 s
C) 1.00 s
D) 0.25 s

A 4.1-kg ball is thrown from the top of a 4-m tall building
(point A) with a speed of 1 m/s at an angle 2 degrees above the
horizontal. If air resistance is negligible, what is the value of
the kinetic energy of the ball as it hits the ground?

2. (15pts, 5pts
each) A ball is thrown from the top of a building that is
H = 40 m height. It has an initial velocity
v0 that is at angle
of = 53° below the horizontal direction, as shown in the
below Figure. The ball hits the ground t = 2.0 s after being
thrown. You may neglect air resistance.
a) Find the magnitude of the initial velocity
v0 of the ball.
b) Find the velocity of the ball just...

A ball, mass is 8 kg, is thrown from the top of a 30 m cliff
with a velocity of 20 m/s straight up. The ball misses the cliff on
the way down. Ignore air resistance. Use work and conservation of
energy to find the following values.
a. what is the work done by gravity while the ball is in the
air?
b. what is the maximum height of the ball?
c. what is the magnitude of the velocity just...

A ball is thrown horizontally with an initial speed of 50m/s
from the top of a building 60m tall
a) How far away from the building will the ball hit the
ground?
b) What is the horizontal component of its velocity when it hits
the ground?
c) Find the magnitude and direction of the velocity when it hits
the ground?

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?
