- A block of mass 4m can move without friction on a horizontal table. This block is attached to another block of
mass m by a string that passes over a frictionless pulley. If the masses of the string and the pulley are negligible,
what is the magnitude of the acceleration of the descending block?

Answers

The magnitude of the acceleration of the descending block is equal to 1.96 m/s².

What is the tension in the string?

Tension can be described as a force acting along the length of a rope or a cable, especially a force that comprises by a flexible medium. Tension can be described as an action-reaction pair of forces acting at each end of the length of the medium. Each endpoint carried tension and force from the weight attached.

Given that the block with mass, M₁ = 4m is placed on the horizontal table.

The block with mass, M₂ = m is attached by a string.

The block (M₂) suspended by the string experiences tension (T) in the upward direction and weight in the downward direction.

M₂g - T = M₂a                                                     ..............(1)

The block (M₁) placed on the table experienced only one force which is tension (T)

T = M₁ a                                                          .....................(2)

From equation (1) and (2):

M₂g -  M₁a  = M₂a  

M₁a  + M₂a  = M₂g

(M₁ + M₂) a =  M₂g

a = M₂g/(M₁ + M₂)

Substitute the value of masses of the blocks:

a = m g /( 4m + m)

a = g/5

a = 1.96 m/s²

Hi there!

We know that:

[tex]W = \Delta KE = \frac{1}{2}m(\Delta v)^2[/tex]

We can begin by solving for the final velocity using the equation:

[tex]v_f = v_i + at[/tex]

The box starts from rest, so:

[tex]v_f = at\\\\v_f = 6(9) = 54 m/s[/tex]

Now, we can find the kinetic energy:

[tex]KE = \frac{1}{2}mv^2\\\\KE = \frac{1}{2}(6)(54^2) = 8748 J[/tex]

Thus:

[tex]W = \Delta KE\\\boxed{W = 8748 J}[/tex]

A young woman walks up 55 steps to the top of a water slide. She slides
down, feet first, all the way to the bottom gaining speed as she goes. If each
step of the slide is.10m tall, how fast will she be going at the bottom?

Answers

Answer:

potential energy PE = M g h

KE at bottom = 1/2 M V^2

Regardless of the slope of the slide the change in energy is the same

1/2 V^2 = g h

V = (2 g h)^1/2 = (2 * 9.8 m/s^2 * 10 m)^1/2 = 14 m / s

Perhaps the question says that h = 55 * .1 = 5.5 m

Then V = (2 * 9.8 * 5.5) = 10.4 m/s

Answer:

not sure, but I thinks it's either Transparent or Reflective

According to the concept of reflection, if  a piece of glass permits light to pass through, then it is considered to be reflective.

What is reflection?

Reflection of light is defined as a property of light ray that when it strikes a smooth surface it bounces back .Objects can be seen due to this property of light.Reflection is produced by all types of waves namely sound waves, light waves, electromagnetic waves.

Reflection of light is governed by laws of reflection which are also called as Snell's laws. According to laws of reflection, angle of incidence and angle of reflection are equal.The incident ray , reflected ray and normal all lie on the same side of the plane.Light travels in a straight line before, after and during the process of reflection.There are 3 types of reflection which are diffuse reflection,specular reflection and glossy reflection.

What is the force that counteracts the thrust force for flight?

Answers

The force which counteracts the thrust force for the flight is known as the drag force, as it opposes the flow.

What is drag force?

Drag is a force that opposes an object's relative motion to a fluid environment in the field of fluid dynamics. It may be among two liquid film (or surfaces) or in between a liquid and a flat wall. The drag force is influenced by velocity, as opposed to other resistive forces like dry contact, which are essentially independent of it.

When a flow is moving at low or high speed, the drag force is equal to the speed for low pressure and to the square of the velocity for high-speed flow. Although viscous friction is what ultimately causes drag, turbulent drag is unaffected by viscosity.

A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces.
