Answer:

They would land at the same time

Explanation:

They would land at the same exact time.

As weird, impossible and unbelievable as it appears. When in a vacuum, every weight, body and material when released from the same height would land on the ground at the same time. This also means that like in the question, a feather and a ball would land at the same time. And just for illustrations as well, a feather and a car would land at the same time as well.

A 28 kg mass suspends from a light rope 18 m long & is held to one side by the horizontal force, F, as shown below.

frutty [35]

Answer: 215.15 N

Explanation:

If we draw a free body diagram of the mass we will have the following:

$\sum{F_{x}}=-Tcos\theta + F=0$ (1)

$\sum{F_{y}}=Tsin\theta - mg=0$ (2)

Where $T$ is the tension force of the rope, $m=28 kg$ the mass, $g=9.8 m/s^{2}$ the acceleration due gravity and $mg$ is the weight.

On the other hand, we can calculate $\theta$ as follows:

$cos\theta=\frac{s}{l}$

$\theta=cos^{-1}(\frac{s}{l})$

Where $s=11.1 m$ and $l=18 m$

$\theta=cos^{-1}(\frac{11.1 m}{18 m})$

$\theta=51.9\°$ (3)

Now, we firstly need to find $T$ from (2):

$T=\frac{mg}{sin\theta}$ (4)

$T=\frac{(28 kg)(9.8 m/s^{2})}{sin(51.9\°)}$

$T=348.69 N$ (5)

Substituting (5) in (1):

$F=Tcos\theta$ (6)

$F=348.69 N cos(51.9\°)$

Finally:

$F=215.15 N$

What is the gravitational energy of a 2.63kg

Elis [28]

Answer:

G.P.E = 368.3

Explanation:

Given the following data;

Mass = 2.63kg

Height, h = 14.29m

We know that acceleration due to gravity is equal to 9.8m/s²

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

$G.P.E = mgh$

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

$G.P.E = 2.63*9.8*14.29$

G.P.E = 368.3

Note: the unit of gravitational potential energy is Joules.

My predicted height was lower than the final height i measured. this is because friction slowed the puck as it was sliding along

LekaFEV [45]

I disagree since friction will cause the ultimate height to be lower than what was anticipated. To reduce the height, resist the action.

<h3> What is the height?</h3>

The vertical distance between an object's top and the bottom is defined as its height.

It is measured in centimeters, inches, meters, and other units. The height of the cliff is obtained by the Newton equation of motion.

My actual height was less than what I had anticipated. this is because the puck's movement along the track was impeded by friction.

To the Khalida, I object. Disagree, since friction will cause the ultimate height to be lower than the anticipated height. To reduce the height, resist the action.

Hence, I disagree with Khalida.

In 1851, Jean Bernard Léon Foucault suspended a pendulum (later named the Foucault pendulum) from the dome of the Panthéon in Pa

lidiya [134]

To solve this problem, it is necessary to apply the concepts of the Simple Pendulum Period. Under this definition it is understood as the time it takes for the pendulum to pass through a point in the same direction. It is also defined as the time it takes to get a complete swing. Its value is determined by:

$T = 2\pi \sqrt{\frac{l}{g}}$

Where,

T= Period

l = Length

g = Gravitaitonal Acceleration

With our values we have tat

$T = 2\pi \sqrt{\frac{l}{g}}$

$T = 2\pi \sqrt{\frac{67}{9.809}}$

$T = 16.413s$

Therefore the period of the pendulum is 16.4s
