A simple pendulum with a length of 2.23 m and a mass of 6.74 kg is given an initial speed of 2.06 m/s at its equi- librium posit

solniwko [45]

Answer:

a) T = 2.997 s

b) K = 14.3 J

c) φ = 0.444 rad

Explanation:

a) Determine its period

The pendulum simple’s period is:

T = 2π $\sqrt{\frac{l}{g} }$

Where l: Pendulum’s length

g = 9.8 m/s2

T = 2π $\sqrt{\frac{2.23}{9.8} }$

T = 2.997 s

b) Total energy

Initially his total energy is kinetic

K = $\frac{mv^{2} }{2}$

K = $\frac{(6.74)(2.06)^{2} }{2}$

K = 14.3 J

c) Maximum angular displacement

φ = $cos^{-1}(1-\frac{E}{mgl} )$

φ = $cos^{-1}(1-\frac{14.3}{(6.74)(9.8)(2.23)} )$

φ = 0.444 rad

SOMEONE HELP PLEASE!!!!(15POINTS)

Bezzdna [24]

Answer: Friction

Explanation:

Friction is a force that opposes the motion of an object on another surface. For example, when a box is pushed along the floor, the floor exerts a frictional force on the box, "resisting" the motion of the box. This force is due to the contact between the molecules of the box and the molecules of the floor, and it is always directed against the direction of motion of the object (so, if the object is moving forward, friction acts backwards).

The magnitude of the friction force is given by:

$F=\mu N$

where $\mu$ is the coefficient friction, which is a number that depends on the materials of the two surfaces, and N is the normal reaction.

aliya0001 [1]

Answer:

D₂= 167,21 cm : Magnitude of the second displacement

β= 21.8° , countercockwise from the positive x-axis: Direction of the second displacement

Explanation:

We find the x-y components for the given vectors:

i: unit vector in x direction

j:unit vector in y direction

D₁: Displacement Vector 1

D₂: Displacement Vector 2

R= resulta displacement vector

D₁= 152*cos110°(i)+152*sin110°(j)=-51.99i+142.83j

D₂= -D₂(i)-D₂(j)

R= 131*cos38°(i)+ 131*sin38°(j) = 103.23i+80.65j

We propose the vector equation for sum of vectors:

D₁+ D₂= R

-51.99i+142.83j+D₂x(i)-D₂y(j) = 103.23i+80.65j

-51.99i+D₂x(i)=103.23i

D₂x=103.23+51.99=155.22 cm

+142.83j-D₂y(j) =+80.65j

D₂y=142.83-80.65=62.18 cm

Magnitude and direction of the second displacement

$D_{2} =\sqrt{(D_{x})^{2} +(D_{y} )^{2} }$

$D_{2} =\sqrt{(155.22)^{2} +(62.18 )^{2} }$

D₂= 167.21 cm

Direction of the second displacement

$\beta = tan^{-1} \frac{D_{y}}{D_{x} }$

$\beta = tan^{-1} \frac{62.18}{155.22 }$

β= 21.8°

D₂= 167,21 cm : Magnitude of the second displacement

β= 21.8.° , countercockwise from the positive x-axis: Direction of the second displacement

Komok [63]

Answer:

yes every action as an equal and and opposite reaction. if you throw a tool then it will give you a reaction and you will move back.

Explanation:

According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.

To understand it better:

Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.

So, if you as an astronaut in the described situation throw your tool in the direction that you are traveling (in the opposite direction of the space station), according to Newton's third law, you will be automatically moving towards the station
