An archer stands at rest on frictionless ice and fires a 0.5-kg arrow horizontally 50.0 m/s. The combined mass of the archer and bow is 60.0 kg. With what velocity does the archer move across the ice after firing the arrow?
1. An archer stands at rest on frictionless ice and fires a 0.5-kg arrow horizontally 50.0 m/s. The combined mass of the archer and bow is 60.0 kg. With what velocity does the archer move across the ice after firing the arrow?
Answer:-Mass of bow=m1=0.5kgMass of man before firing gun=60-0.5=59.5kg=m2Initial velocity=u_1=50m/sRecoil velocity=u2=?
According to law if conservation of linear momentum.
[tex]\boxed{\sf m_1u_1=m_2u_2}[/tex]
[tex]\\ \sf\longmapsto (0.5)(50)=59.5u_2[/tex]
[tex]\\ \sf\longmapsto 25=59.5u2[/tex]
[tex]\\ \sf\longmapsto u_2=\dfrac{25}{59.5}[/tex]
[tex]\\ \sf\longmapsto u_2=0.4m/s[/tex]

3. 5. An archer tries to hit a target that is 30 m away from him. He can release the arrowat 20 m/s neglecting air resistance, estimate the angle at which the archer shouldaim to compensate for fall of the arrow due to gravity.
Solution:
The formula for the range of a projectile is
R = vi² sin 2θ / g
where:
R = range
vi = initial velocity
θ = angle of release (from the horizontal)
g = acceleration due to gravity
g = 9.81 m/s² (9.8 m/s² in some books)
Listing the given values
R = 30 m
vi = 20 m/s
Solving for θ
R = vi² sin 2θ / g
30 m = [(20 m/s)²(sin 2θ)] / 9.81 m/s²
(30 m)(9.81 m/s²) = (400 m²/s²)(sin 2θ)
294.3 m²/s² = (400 m²/s²)(sin 2θ)
sin 2θ = (294.3 m²/s²) / (400 m²/s²)
sin 2θ = 0.73575
2θ = Arcsin (0.73575)
2θ = 47.3706°
θ = 47.3706° / 2
θ = 23.69°
θ ≈ 24°
Therefore, the archer should aim at an angle of 24° to compensate for fall of arrow due to gravity.

7. Archer is 3.48 meters away from the wall outside the classroom (can be changed) that is 3.48 meters high. She wanted to put a décor on the decorative block. How far is the decorative block to Archer on the ground?
Answer:
about 4.92 meters
i just rounded it:)
Step-by-step explanation:
i used pythagorean theorem
a²+b²=c²
substitute the measures,
(3.48)²+(3.48)²=c²
12.1104 + 12.1104= c²
24.2208=c²
c= √24.2208
= 4.921
yes i used calculator

11. an archer released the arrow from her bow to hit the bulls eye. what does the arrow make with the archer's body?
Answer:
Assuming that the archer is right-handed and is standing perpendicular to the target, when the arrow is released, it will travel straight towards the target while the bow arm will move slightly forward and to the left, and the drawing hand will move slightly back and to the right. This is known as the Archer's Paradox, which refers to the bending of the arrow as it is released due to the oscillation of the bow limbs.
Therefore, at the moment of release, the arrow makes an angle with the archer's body, with the exact angle depending on the specific form and technique used by the archer. However, it is generally a small angle and does not have a significant impact on the trajectory of the arrow.
Answer:
The arrow will follow the trajectory determined by the angle at which it was shot, which will depend on factors such as the distance to the target, the weight of the arrow, the draw weight of the bow, and the archer's technique.
Step-by-step explanation:
However, to answer the specific question of what angle the arrow makes with the archer's body, it is difficult to give a single answer as it will depend on the archer's stance and position at the moment of release, as well as the trajectory of the arrow.
In general, though, the arrow is likely to make an angle with the archer's body that is determined by the position of the bow at the moment of release and the trajectory of the arrow. This angle can vary from a few degrees to a significant angle depending on the factors mentioned above.

History of photography ppt
History of photography ppt1. People have been keeping visual records of themselves and the things around them since prehistoric times, recording images that range from carefully drawn hieroglyphics to pictures taken on the surface of the moon. Each image is an attempt to communicate from one person to another the things we see. Photography, which means literally “writing with light”, gives us the means to record and examine our day-to-day activities and experiences. Unlike the casual glance, which often “sees” only the major elements of a scene, a photograph records the tiniest of details. It then allows us time to study and understand each minute element. A photograph preserves what memory cannot.

Questio
2. In what aspect does the knowledge in projectile motion help the archer?
Answer:
Knowing about projection motion will help the archer to hit the right spot. Having the advantages of it will help the archer to change the angle according to the distance of the target using the force of gravity to hit the right spot.
Explanation:
Projectile motion is seen everyday in real life.
For example:
When shooting the ball to the ring when you play basketball. You will notice that the ball does not go straight to the ring. It creates an arc when you shoot it. Everything you throw in the air will always comes down. That is when you will notice the relationship of gravity in projectile motion.
