Question

A cannon is fired at an angle of 50 ° with the horizontal. If the cannonball has an initial velocity of 757 feet per second, how far (horizontally) will the shot travel? Assume the initial height of the projectile is 0 feet, and neglect air resistance.

Answer #1

(Figure
1) A cannonball is fired
horizontally from the top of a cliff. The cannon is at
height H = 80.0m
above ground level, and the ball is fired with
initial horizontal speed v0.
Assume acceleration due to gravity to be g = 9.80m/s2
.
Part
A
Assume that the cannon is fired at
time
t=0 and that the
cannonball hits the ground at time tg. What is the
y position of the cannonball at the time
tg/2?
Answer numerically...

A 9.8 kg cannonball was fired from a cannon straight up with an
initial velocity of 42 m/s.
(A) Assuming that all its initial kinetic energy was transformed
into gravitational energy, what is the maximum height that the
cannonball could reach?
(B) Suppose that 20% of its initial kinetic energy was lost due
to friction with the air (air resistance). What is the maximum
height that the cannonball could now reach?
(C) How long will it take, after the cannon...

A cannon is fired over level ground with its barrel at an angle
of 45.0o to the horizontal. The shell takes 51 s to hit the ground.
Neglect air resistance and the height of the muzzle. How far from
the cannon did the shell land? The units are not in the mks system
here, but the answer is unambiguous.

A cannonball is fired with an initial velocity of 100 m/s at an
angle of 35 degrees above the positive x-axis.
The target is the enemy King's tower.
The cannon is positioned 300 m from the base of the King's
tower, on a flat, horizontal field. The cannonball takes 3.66 s to
strike the tower after it is fired.
1. At what height on the tower does the cannonball strike?
2. What is the approximate magnitude of the cannonball's
velocity...

A cannonball, weighing 19.1 kg, is shot from a cannon sitting on
a ledge a height of 2.50 m above sea-level toward
a castle. It is shot with a velocity of 42.0 m/s at an angle of
55.0° above the horizontal. The cannonball impacts on the
castle wall 5.70 s later.
(a) At what height, in feet, does the cannonball hit the castle
wall?
(b) What is the cannonball’s impact velocity (magnitude and
direction) just before hitting the cliff?
(c)...

A
con on at ground level launches a cannonball horizontally. If the
cannon fires with a velocity of 28.3m/s and at an angle of 30
degrees how far will the cannonball travel?

A
projectile is fired from cannon (مدفع) at ground level at 45
degrees with respect to the horizontal. Neglect air resistance,
When the projectile reaches maximum height, The ratio of the
horizontal distance traveled by the projectile to maximum height
is

A cannonball is fired at a tower with an initial speed of 50.0
m/s and at an initial angle of 20.0° above the horizontal. If the
tower is a horizontal distance of 150 m away from the cannon, how
long does it take for the cannonball to hit the tower? The effects
of air resistance in this situation are negligible.

A 19.0-kg cannonball is fired from a cannon with muzzle speed of
1150 m/s at an angle of 42.0° with the horizontal. A second ball is
fired with the same initial speed at an angle of 90.0°. Let y = 0
at the cannon.
(a) Use the isolated system model to find the maximum height
reached by each ball. hfirst ball =? m
hsecond ball = ? m
(b) Use the isolated system model to find the total mechanical
energy...

A 4 kg mortar shell is fired at an angle of 60° above the
horizontal with an initial speed of v0. At its highest point its
speed is 120 m/s. (a) At this highest point, what is the change in
its gravitational potential energy relative to its initial launch
position? Neglect air resistance? (b) How far above the launch
point did the mortar travel to get to its highest point? Neglect
air resistance
