Answer:
It would help Carlos stop sliding down and he would stay in his place in the air.
Explanation:
According to Newton's 1st Law of Motion, a body is said to be at rest or uniform motion when no net force is acting on it. This explains that when the tension in the rope becomes equal to Carlos' weight, the net force becomes zero which means the body (Carlos), is at rest and remains in the air instead of sliding down the rope.
It is a chemical change because the salt is dissolving.
Answer:
a) 17 N
b) 21 N
Explanation:
At the 3 o'clock position, the sum of the forces towards the center is:
∑F = ma
T = m v² / r
19 = m v² / r
At the 12 o'clock position, the sum of the forces towards the center is:
∑F = ma
T + mg = m v² / r
T + (0.18)(9.8) = 19
T = 17.2 N
At the 6 o'clock position, the sum of the forces towards the center is:
∑F = ma
T − mg = m v² / r
T − (0.18)(9.8) = 19
T = 20.8 N
Rounding to two significant figures, the tensions are 17 N and 21 N.

Answer: D) 1.587 E3 N toward the center of the circle
This is the same as saying 1.587*10^3 newtons, or we can say 1587 newtons
=================================================
Work Shown:
m = mass = 660 kilograms
v = velocity = 11.5 meters per second
r = radius of circle = 55.0 meters
-------------
F = centripetal force = inward pulling force toward center of circle
F = (m*v^2)/r
F = (660*11.5^2)/55
F = 1587
F = 1.587 * 10^3
F = 1.587 E 3
The "E 3" notation is what many calculators display scientific notation to be
The units for the force here are in newtons.
The force is pulling on the object toward the center of the circle, which helps keep the car on the circular path, rather than it going off on a tangent.
