Answer:

Physics is the study of matter and the way living things behave everyday....It is related to maths in how we measure the way objects or people do specific things physics has many branches under it that can be helpful too.....Physics teaches us about the world,about the mechanical things we do about air,space,matter about the solar system and about simple machines and things that we do everyday in life.... What we do everyday is related to physics....

Two ropes support a load of 478 kg. The two ropes are perpendicular to each other, and the tension in the first rope is 2.2 time

sveta [45]

Answer:

T₂ = 1937.68 N

Explanation:

First, we will calculate the weight of the object:

$W = mg = (478\ kg)(9.81\ m/s^2)\\W = 4689.18\ N$

Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,

$T = \sqrt{T_1^2+T_2^2}\\$

where,

T = Resultant Tension

T₁ = Tension in rope 1

T₂ = Tension in rope 2

According to the given condition tension in the first rope is 2.2 times the tension in the second rope:

T₁ = 2.2 T₂

Therefore

$T = \sqrt{(2.2T_2)^2 + T_2^2}\\\\T = 2.42T_2$

Now, the weight of the object must be equal to the resultant tension for equilibrium:

$T = W\\2.42T_2 = 4689.18\ N\\\\$

T₂ = 1937.68 N

Sam's job at the amusement park is to slow down and bring to a stop the boats in the log ride. You may want to review ( pages 29

hjlf

The work that Sam should do in order to stop is the boat is the same as that of the kinetic energy of the object in order to counter its motion. Kinetic energy is calculated through the equation,
KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity.
Substituting,
KE = 0.5(1200kg)(1.2 m/s)²
KE = 864 J

Displacement vectors of 4 km north, 2 km south, 5 km north, and 5 km south combine to a total displacement of

valentinak56 [21]

south = -(north)

Displacement = (4 km north) + (2 km south) + (5 km north) + (5 km south)

Displacement = (4 km north) - (2 km north) + (5 km north) - (5 km north)

Displacement = (4 - 2 + 5 - 5) km north

Displacement = 2 km north
