Angelica has sprained her ankle and needs to stay off it for a few weeks, which is really frustrating because she is on the track team. She is worried that a prolonged period of inactivity will hurt her training. After about 10 days, she thinks that she can start working out gradually if she takes painkillers right before her workout. What is the BEST response to Angelica?
OPTIONS:
A.
She could really injure herself with this plan since she will not feel pain.
B.
Trying it once or twice and seeing how she feels is probably the best way to go.
C.
It is a common technique and lots of athletes practice injured so she will be fine.
D.
The damage from working out is probably less than the issue exercise will create.

What is ankle sprain?A sprain takes place when your ankle is compelled to move out of its regular place, causing one or more of the ligaments in your ankle to stretch, partially tear, or completely tear.
A sprained ankle can be caused by a fall that causes your ankle to twist. Landing on your foot awkwardly after jumping or pivoting.
You should avoid strenuous exercises, such as running, until the pain and swelling have subsided, but you should keep moving so that the muscles and ankle do not stiffen. Once your ankle is less painful, begin some gentle exercises.
As she is having ankle sprain, and she is planning to take pain killers and start to work out, this can cause her even more problem as she will not feel any pain.
Thus, the correct option is A.

An book fell from a shelf 1.5 meters from the ground. If it took the book 3 seconds to hit the ground, what was the velocity of the book?
The initial velocity of the book before its hits the ground is 14.2 m/s.
The given parameters;
height of the book above the ground, h = 1.5 mtime of motion of the book, t = 3 secondsThe initial velocity of the book is calculated as follows;
h = ut + ¹/₂gt²
where;
u is the velocity of the book1.5 = 3u + (0.5 x 9.8 x 3²)
1.5 = 3u + 44.1
3u = 1.5 - 44.1
3u = -42.6
[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]
Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

A steel projectile is shot horizontally at 54 m/s from the top of a 357 m tower. How far
from the base of the tower does the projectile hit the ground?
Hi there!
We can begin by solving for the time it takes the projectile to reach the ground.
Use the equation:
[tex]t = \sqrt{\frac{2h}{g}}[/tex]
Plug in the given height:
[tex]t = \sqrt{\frac{2(357)}{9.8}} = 8.536 s[/tex]
Use the equation:
d = vt, to solve for the horizontal distance:
d = (54)(8.536) = 460.944 m
What is frequency measured in? What is the amplitude?
Answer:
The units of frequency are hertz. As 1 hertz is equal to one cycle per second.
Amplitude is the maximum displacement of the waves or the distance from rest to crest and is measured in meters or centimeters or millimeters.

Answer:
The answer is static friction. This is the friction that involves objects that do not move.
Explanation:
Friction is a force which opposes the motion of one object moving relative to another. static friction and kinetic friction are the two type of friction.
Static friction is that type of friction which keeps an object at rest. Force must be applied greater than static friction to move an object. Therefore it is the static friction which helps the pile of rocks from falling apart.

why does lowered air pressure allow water to boil at room temperature
Answer:
As ambient air pressure decreases, molecules evaporating from a boiling liquid meet less resistance from air molecules and enter the air more easily. Because the vapor pressure can be reduced, the temperature needed to boil the liquid is also reduced.
Explanation:
Answer:
Less force pushes down on the liquid, making it easier for gas to escape.

A 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. What is the magnitude of the net force causing it to slow down?
The magnitude of the net force causing the 2300kg car to slow down is 6900N
HOW TO CALCULATE FORCE:
The net force applied on a moving object can be calculated by multiplying the mass of the object by its acceleration. That is;Force (N) = mass (kg) × acceleration (m/s²)According to this question, a 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. The net force causing the car to stop can be calculated as follows:F = 2300kg × 3m/s²
F = 6900N
Therefore, the magnitude of the net force causing the 2300kg car to slow down is 6900N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults

A 1.35 kg block is pulled across a
flat, frictionless floor with a 3.07 N
force at 32.0° above horizontal.
What is the acceleration of the block?
Answer:
F=ma
3.07=1.35(a)
3.07/1.35 = a
a=2.27m/s^2
Explanation:
Since the question gives us both the force and mass of the object we can use the f= ma equation and just plug in both the force and mass and just solve for acceleration. I believe the degree listed in the question is just there to throw you off.
Henry is at the state fair. At one booth he throws a 0.70 kg ball forward with a velocity of 22.0 m/s in order to hit a 0.15 kg bottle sitting on a shelf. When the ball makes contact the bottle goes flying forward at 29.0 m/s. What is the velocity of the ball after it hits the bottle?
The velocity of the ball after it hits the bottle is 15.8 m/s
Let m₁ represent the mass of the ball, m₂ the mass of the bottle, u₁ the velocity of ball before impact, u₂ the velocity of bottle before impact, v₁ the velocity of ball after impact and v₂ the velocity of bottle after impact.
Given that:
m₁ = 0.7 kg, m₂ = 0.15 kg, u₁ = 22 m/s, u₂ = 0, v₂ = 29
momentum before impact = momentum after impact, hence:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.7(22) + 0.15(0) = 0.7v₁ + 0.15(29)
0.7v₁ = 11.05
v₁ = 15.8 m/s
Therefore the velocity of the ball after it hits the bottle is 15.8 m/s
