Question

Cite your answers in SI units and to three significant figures.

An archer standing on a 15 degree slope shoots an arrow at an angle of 21 degrees above the horizontal. How far below its original point of release does the arrow hit if it is shot with a speed of 38 m/s from a height of 1.78 m above the ground?

Answer #1

An archer shoots an arrow from 4 feet above the ground at an
initial velocity of 260 ft/sec at an angle of 30 degrees above the
horizontal. Find the maximum height of the arrow. If the archer was
shooting at a hog that was 1500 feet away, was the shot too high,
too low or on target? (assume the only forces acting on the arrow
after it is shot is the force due to gravity

An
archer shoots an arrow at a 7.50m distant target; the bulls eye of
the target is at the same height as the release height of the
arrow. (A) At what angle must the arrow be released to hit the
bullseye if it’s initial speed is 35.0m/s? In this part of the
problem, explicitly show how you follow the steps involved in
solving projectile motion problems. (B) there is a large tree
halfway between the archer and the target with...

An archer shoots an arrow toward a wall 50 yards away, with an
initial velocity that makes an angle of 45 degrees with the
horizontal. If the arrow was released from the shoulder level (4
feet above the ground) and the arrow strikes the wall 35 yards
above the ground, find each of the following:
a.) The initial velocity of the arrow
b.) The time it took to reach the wall.

You would like to shoot an orange in a tree with your bow and
arrow. The orange is hanging 5.00 m above the ground. On your first
try, you fire the arrow at 32.0 m/s at an angle of 30.0° above the
horizontal from a height of 1.30 m while standing 54.0 m away.
Treating the arrow as a point projectile and neglecting air
resistance, what is the height of the arrow once it has traveled
the 54.0 m horizontally...

A 2.0 m tall basketball player is standing a horizontal distance
of 7.0 m away from a basketball hoop. The height of the hoop is 3.0
m above the floor. The basketball player throws the ball at an
angle of 60 degrees above the horizontal, and from an initial
height of 2.0 m above the floor. (Use g= 9.8 m/s2 and neglect air
friction effects). Give your answer to 2 significant figures. a)
How long does it take for the...

A water balloon is launched at a speed of 27 m/s and an angle of
36 degrees above the horizontal. The water balloon hits a tall
building located 27 m from the launch pad. At what height above the
ground level will the water balloon hit the building? Calculate the
answer in meters (m) and rounded to three significant figures.
Please show work :)

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...

You are a Pirate Captain on a journey. Some of your newly
recruited gunners still haven't gotten the swing of things and set
all the cannons at different angles. Halfway through the journey,
you spot a Royal Navy ship and have to go into battle with the crew
that you have.
Along the ship's port (left) side you notice an equal number of
cannons elevated at 30 degrees, 40 degrees, and 60 degrees
respectively. Your cannons fire frictionless projectiles with...

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
