Question

If
an arrow of .088 kg is shot by a bow. If the average force is 110 N
over a distance of 78 cm. What is the speed of the arrow when it
comes out of the bow?

Answer #1

An arrow is fired straight up from a bow. The arrow is in
contact with the bow string through a distance that is
approximately the length of the arrow. The arrow travels upward
about forty meters, and returns to hit the ground. When the arrow
is examined, just a little past the arrowhead is buried into the
ground. Of the portions of the motion described, which one has the
highest magnitude of acceleration? Explain.

1a) An archer pulls back on his bow string with a draw force of
162N. When the archer releases the string, it remains in contact
with the arrow for 12.4 ms. What impulse is given to the arrow by
the bow? 1b) At what speed is an 11.9-g arrow shot? 1c) What is the
arrow's kinetic energy immediately after being shot? 1d) The arrow
pierces an 123-g apple at the same height at which it was
originally shot. Assuming a...

A 25.0 g arrow is released from a bow by George through an 8.00
cm thick grapefruit sitting on top of a log. The arrow enters the
grapefruit at 32.0 m/s and emerges at 27.0 m/s in the same
direction.
a) Sketch a free body diagram of the arrow when passing through the
grapefruit.
b) What is the acceleration of the arrow?
c) With what force has the grapefruit resisted the arrow?

Katniss pulls back a
bow a distance of 0.51 m with a force of 215 N and lets it fly.
What is the spring constant of the bow? ANSWER 1433.33
If kinetic energy is
equal to Elastic Potential energy in the bow, what is the velocity
of the arrow after it leaves the bow? (Assume the arrow has a mass
of .033 kg) You have to use the spring constant k you
calculated in the previous problem. ANSWER 210.48
If...

You are watching an archery tournament when you start wondering
how fast an arrow is shot from the bow. Remembering your physics,
you ask one of the archers to shoot an arrow parallel to the
ground. You find the arrow stuck in the ground 62.0 m away, making
a 2.8 ∘ angle with the ground. Ignore all possible aerodynamic
effects on the motion of the arrow. Use 9.80 m/s2 for the
acceleration due to gravity.

You shoot an arrow from a compound bow straight up into the
air, and it goes 7.6 m above the height you shot it from before it
falls back down. If you now shoot the arrow at a 22° angle
above the horizontal, what will its new maximum height be?

1. A 61 g firing pin in a horizontal rifle bolt is attached to a
spring. The shooter applies an average force of 57 N to compress
the spring 4.1 cm.
(a) Calculate the spring constant. N/m
(b) Ignoring friction, calculate the maximum speed of the pin
after the spring is released.
2.An archer uses her bow to aim a 150 g arrow vertically upward.
The effective spring constant of the bow at full flex is 990 N/m.
When released, the...

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...

Robin would like to shoot an orange in a tree with his bow and
arrow. The orange is hanging ?f=5.00 myf=5.00 m above the ground.
On his first try, Robin looses the arrow at ?0=32.0 m/sv0=32.0 m/s
at an angle of ?=30.0°θ=30.0° above the horizontal. The arrow has
an initial height of ?0=1.50 m,y0=1.50 m, and its tip is ?=53.0
mx=53.0 m away from the target orange.
Treating the arrow as a point projectile and neglecting air
resistance, what is...

A 0.1-kg ball is attached to the end of an ideal spring having a
force constant (spring constant) of 600 N/m.
If the spring is compressed 18 cm and released, what is the
speed of the ball when it reaches a distance of 12 cm from the
equilibrium position?
Determine the period.
Determine the amplitude.
Determine the maximum speed.
Determine the total energy.
