The distance traveled by the arrow and horizontal velocity are directly proportional, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.
<h3>
Time of motion of the projectile</h3>
If the horizontal distance the projectile would travel before hitting the target is 70.67 m, the time of motion of the projectile is calculated as;
X = Vx(t)
t = X/Vx
t = X/Vcosθ
t = (70.67) / (45 x cos10)
t = 1.6 s
When the archery target is moved further away from the archer, the archer needs increase the initial velocity of the arrow assuming the angle of projection is constant.
Since the distance and horizontal velocity are directly proportional to each other, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.

Explanation:
The somatic nervous system coordinates the voluntary control of movement in the body system.
The nervous system is made up of the central nervous system and peripheral nervous system.
The peripheral nervous system is made up of the nerves that branches into the body from the spinal cord.
- It consist of the somatic nervous system and the autonomous nervous system.
- The somatic nervous system controls the voluntary actions of movement in the body.
- It coordinates the reflex arc.

Answer:
The angle between two forces is 165 degrees.
Explanation:
We have,
Force 1,
Force 2,
Resultant of two forces, F = 8 N
It is required to find the angle between two forces. The resultant of two force is given by the formula as follows :
is the angle between F₁ and F₂
So,
So, the angle between two forces is 165 degrees.
Answer:
999 V
Explanation:
Charge deposited on the capacitor
= current x time
= 2 x 10⁻³ A x 5 x 10⁻³
= 10⁻⁵ C
increase in volt = charge deposited / capacitance
10⁻⁵ / .1 x 10⁻⁶
= 10² V
= 100 V
voltage in the beginning = -1 V
voltage at the end
= -1 + 100
99 V .
Both balls hit the ground at the same time.
We've known this fact for about 500 years (since Galileo),
and we've known WHY for about 300 years (since Newton).
