a bobsled team emerges from a downhill track onto a horizontal straight track intended to slow the sled to a stop. the total mas

s of the bobsled and team is 488 kg. they emerge with speed 54 m/s. if the frictional force slows them to a stop at a constant 3.1 m/s2, how much work is done on the bobsled team while they stop?

Work is done on the bobsled team while they stop is <u>13,176 Nm</u>

Work, in physics, degree of electricity switch that happens when an item is moved over a distance with the aid of an outside pressure at the least a part of that is carried out in the route of the displacement.

<u>Calculation:-</u>

mass = 488 Kg

speed = 54 m/s

a = 3.1 m/s²

displacement

V² = U² -  2as

0 = 54 - 2× 3.1 S

S = 54/6.2

  = 8.71 m

Work done = force × displacement

                    = mass × acceleration × displacement

                    = 488 × 3.1 × 8.71

                    =<u> 13,176 Nm</u>

The work done via a pressure is the made of the displacement and the issue of the implemented force of the item within the path of displacement. while we push a block with a little force. The body moves with some acceleration, and work is executed. The paintings finished by pressure are defined to be manufactured from a thing of the pressure within the direction of the displacement and the significance of this displacement.

Which of the following accurately describe some aspect of gravitational waves? Select all that apply.
steposvetlana [31]
<h2>Answers:</h2>

-The first direct detection of gravitational waves came in 2015

-The existence of gravitational waves is predicted by Einstein's general theory of relativity

-Gravitational waves carry energy away from their sources of emission

<h2>Explanation:</h2>

Gravitational waves were discovered (theoretically) by Albert Einstein in 1916 and "observed" for the first time in direct form in 2015 (although the results were published in 2016).  

These gravitational waves are fluctuations or disturbances of space-time produced by a massive accelerated body, modifying the distances and the dimensions of objects in an imperceptible way.  

In this context, an excellent example is the system of two neutron stars that orbit high speeds, producing a deformation that propagates like a wave,<u> in the same way as when a stone is thrown into the water</u>. So, in this sense, gravitational waves carry energy away from their sources .

Therefore, the correct options are D, E and F.

The law of reflection states that if the angle of incidence is 76 degrees, the angle of reflection is ___ degrees.
Ann [662]
Answer is 76 degrees. 

The law of reflection states that when a line is reflected on a straight plane, the angle of incidence is equal to the angle of reflection. In this case, the angle of incidence and the angle reflection are 76 degrees.

To determine the location of the center of mass (or center of gravity) of a car, the car is drivenover a scale on a horizontal f
just olya [345]

Explanation:

It is given that,

When the front wheels are over the scale, the weight recorded by the scale is 5800 N, F₁ = 5800 N

When the rear wheels are over the scale, the scale reads 6500 N, F₂ = 6500

The distance between the front and rear wheels is measured to be 3.20 m, x₂ = 3.2 m

We need to find the location of center of mass behind the front wheels. Let the center of is located at a distance of x₁. Thus balancing the torques we get :

5800\times x_2=6500\times (3.2-x_2)

On solving the above equation we get, x₂ = 1.69 m

So, the center of mass is located at a distance of 1.69 meters behind the front wheels.
