The inquiry is unfinished. Below is the complete question.

The attached map depicts Olivia's journey to the coffee shop. She rides her bike south for 0.9mi to Broadway after starting at Loomis. Next, she turns east onto Broadway, traveling 0.8mi until the road curves, and then she proceeds another 1.4mi to reach the shop.

What is the total displacement magnitude of her journey?

What direction does the total displacement of her journey take?

Response: Magnitude = 2.6mi

              Direction: 54.65° east

Clarification: Displacement refers to the change in position of a moving entity.

There are various methods to calculate total displacement. In this scenario, the method of Perpendicular Components of a Vector will be applied.

This method calculates total displacement as follows:

\Delta d_{t}=\sqrt{(\Delta d_{x})^{2}+(\Delta d_{y})^{2}}

\theta=tan^{-1}(\frac{\Delta d_{y}}{\Delta d_{x}})

\Delta d_{x} represents the x-component of the total displacement, which is the total of all individual x-components;

\Delta d_{y} stands for the y-component of the total displacement, calculated by summing all individual y-components;

θ signifies the angle of the resultant displacement;

In Olivia's case, there is no x-component for the first leg, and for the last segment, the biking path acts as the hypotenuse of a right triangle. Therefore, the x-component of that triangle is:

sin30=\frac{x}{1.4}

\frac{1}{2} =\frac{x}{1.4}

x = 0.7

Consequently,

\Delta d_{x} = 0 + 0.8 + 0.7

\Delta d_{x} = 1.5

Regarding the y-component, there’s no y-component in the second portion of Olivia's ride, and in the last segment:

cos30=\frac{y}{1.4}

\frac{\sqrt{3} }{2} =\frac{y}{1.4}

y = 1.21

Thus,

\Delta d_{y} = 0.9 + 0 + 1.21

\Delta d_{y} = 2.11

The total displacement is

\Delta d_{t}=\sqrt{(1.5)^{2}+(2.11)^{2}}

\Delta d_{t}=\sqrt{6.7021}

\Delta d_{t}= 2.6

The magnitude of Olivia's total displacement is 2.6mi

Connecting the starting and ending points on the map forms a vector directed eastward, at an angle of:

\theta=tan^{-1}(\frac{2.11}{1.5})

\theta=tan^{-1}(1.41)

θ = 54.65°

The direction of the total displacement is 54.65° East.

Softa [913]

Respuesta:

Opción e

Explicación:

La Ley de Gravitación Universal indica que toda masa puntual atrae a otra masa puntual en el universo con una fuerza que se dirige en línea recta entre los centros de masa de ambos, siendo esta fuerza proporcional a las masas de los objetos y inversamente proporcional a su separación. Esta fuerza atractiva siempre es dirigida del uno hacia el otro. La ley es aplicable a objetos de cualquier masa, sin importar su tamaño. Dos objetos grandes pueden ser considerados masas puntuales si la distancia entre ellos es considerablemente mayor que sus dimensiones o si presentan simetría esférica. En tales casos, la masa de cada objeto puede ser modelada como una masa puntual en su centro de masa.

La misma fuerza actúa sobre ambas bolas.

A bus slows down uniformly from 75.0 km/h to 0 km/h in 21 s. How far does it travel before stopping?
Yuliya22 [1153]

1 hour = 3,600 seconds
1 km = 1,000 meters

75 km/hour = (75,000/3,600) m/s = 20-5/6 m/s

The mean speed during the deceleration is

                                   (1/2)(20-5/6 + 0) = 10-5/12 m/s.

Traveling at this average speed for 21 seconds,
the bus covers

                        (10-5/12) × (21) = 218.75 meters.

a force of 6lbs acts on an object with a weight of 35 lbs on earth. determine the objects acceleration. final answer must be 5.5
kicyunya [1025]
Weight of the object = 35 lbs
F = ma
m = F/a = 35/32 (with acceleration of 32 ft/s²)
m= 1.09

Again applying the same formula,
a = F/m
a= 6/1.09
a= 5.489

Thus, the acceleration is approximately 5.5 ft/s²!!

the minute hand on a clock is 9 cm long and travels through an arc of 252 degrees every 42 minutes. To the nearest tenth of a ce
Ostrovityanka [942]

Answer:

The distance covered by the minutes hand is 39.60 cm.

Explanation:

Note: A clock has a circular shape, where the minutes hand acts as the radius, and its motion creates an arc.

Length of an arc is calculated as ∅/360(2πr)

L = ∅/360(2πr).................... Equation 1π

Here, L represents the arc’s length, ∅ is the angle made by the arc, and r is the arc’s radius.

Given: ∅ = 252°, r = 9 cm, π = 3.143.

Upon substituting these values into equation 1,

L = 252/360(2×3.143×9)

L = 0.7×2×3.143×9

L = 39.60 cm.

Thus, the distance traversed by the minutes hand is 39.60 cm.

The gas tank of Dave’s car has a capacity of 12 gallons. The tank was 38 full before Dave filled it to capacity. It cost him $2.
Sav [1105]

Answer:

$ 18.75

Explanation:

Given:

Dave's car has a capacity of 12 gallons.

If the tank is at 3/8 full prior to filling:

The cost of gasoline per gallon is $2.50.

The volume Dave needs to fill:

=1 - \dfrac{3}{8}

=\dfrac{5}{8} of full tank

=\dfrac{5}{8}\times 12

Dave must fill 7.5 gallons.

Total amount Dave will pay:

7.5 gallons x $2.50 =

$ 18.75

Thus, Dave will spend $ 18.75 to completely fill the tank.
