Question

A cannon, elevated 40o above the horizontal, is fired at a castle wall 720m away on level ground. The initial speed of the cannonball is 100m/s.

a. What are the initial horizontal (x-direction) and vertical (y-direction) components of the velocity?

b. How long will it take for the cannon ball to hit the wall?

c. How high on the wall does the cannon ball hit?

Q3: A cannonball with an initial height of 1.5 meter above the
ground is fired from a cannon at an angle of θ above the horizontal
and with initial velocity of 40 m/s. The cannonball travels a
horizontal distance of 30 meters and passes over a 14 meter high
castle wall. Find the initial firing angle θ How much time it takes
for the ball to pass over the castle wall ?. Find the velocity
(magnitude and direction ) if...

a cannon fires a 10.0kg cannon ball, 1.0m above the ground, and
20 degress to the horizontal, with an initial speed of 100m/s. A
castle 500m away has a wall that is 24.3m high.
a) at what distance above the castle wall does the cannon ball
pass?
b)calculate the average force that the cannon applied to the
cannon ball. The cannon ball was in the cannon for 0.02seconds
c) what is the vertical acceleration of the cannon ball at the...

King Arthur's knights fire a cannon from the top of the castle
wall. The cannonball is fired at a speed of 58 m/s and an angle of
45°. A cannonball that was accidentally dropped hits the
moat below in 1.97 s.
How far from the castle wall does the cannonball hit the
ground?
What is the ball's maximum height above the ground?

King Arthur's knights fire a cannon from the top of the castle
wall. The cannonball is fired at a speed of 40 m/s and at an angle
of 35°. A cannonball that was accidentally dropped hits the moat
below in 1.2 s.
(a) How far from the castle wall does the cannonball hit the
ground?
(b) What is the ball's maximum height above the ground?

King Arthur's knights fire a cannon from the top of the castle
wall. The cannonball is fired at a speed of 60 m/s and at an angle
of 27°. A cannonball that was accidentally dropped hits the moat
below in 1.0 s. (a) How far from the castle wall does the
cannonball hit the ground? Incorrect: Your answer is incorrect. m
(b) What is the ball's maximum height above the ground? m

(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?

1. A cannon ball is fired from a giant cannon whose length is
1.00 x 102 m. The cannon ball leaves the
barrel at a speed of 99.5 m/s:
a. What is the acceleration of the cannon ball while in the
cannon? Show all work.
The cannon ball (above) leaves the barrel at ground level at an
angle of 60.0o from the ground and travels with minimal
air resistance until impacting on the ground some distance
away.
b. Calculate the initial...

Q1:
A train accelerate from 0 m/s to 36 m/s in 12 seconds and
continues for 50 seconds at 36 m/s . The driver then brakes
strongly to stop in 26 m.
Find the constant acceleration of the train for the first 12
s
Find the total displacement traveled by train.
Find the acceleration for the braking phase.
How long does it take the train to stop from when the brakes
are first applied.
Q2:
A rocket is fired vertically...

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.

The physics of a fired canon ball.
A cannon ball is fired with a velocity of 125 m/s at 25.0° above
the horizontal.
Determine the maximum height the cannon ball reaches in its
path.
Determine the time it takes to reach maximum height.
Determine the hang time of the cannon ball.
Determine the range of the cannon ball.
Draw a sketch of the motion of the projectile including the
horizontal and vertical components of velocity when the projectile
strikes the...
