How to find kinetic energy

Physics

Answer:

Explanation:

Kinetic energy is the energy of movement. To find the kinetic energy, you need to...

1.) Check out the object mass and velocity from the question.

2.) Square the velocity value and multiply it with mass of the object.

3.) Divide the product by 2 to get the kinetic energy value.

The formulas to calculate kinetic energy is given by

Kinetic Energy = ½ * m * v²

m = (2 * KE) / v²

v = √((2 * KE) / m)

The "m" is mass, and the "v" is velocity, and the "KE" is kinetic energy.

Or where can you see Kinetic energy?! People who are moving, they can be sprinting, or jogging, or walking, or jumping, any type of movement.

Even you typing is kinetic energy since you are moving your hands to be able to type. Any little thing can be kinetic energy, if you're still, it's called potential energy since something remains at rest.

Hope this helped!

Have a supercalifragilisticexpialidocious day!

Tarzan, who weighs 849 N, swings from a cliff at the end of a 18.0 m vine that hangs from a high tree limb and initially makes a
loris [4]

Answer:

Part a)

T = 342.5 \hat i + 675\hat j

Part b)

F_{net} = 342.5\hat i - 174\hat j

Part c)

F = 384.2 N

Part d)

\theta = 333 degree

Part e)

a = 4.4 m/s^2

Part f)

\theta = 333 degree

Explanation:

Part a)

Magnitude of tension force is given as

T = 757 N at 26.9 degree with vertical

T = 757 sin26.9 \hat i + 757 cos26.9 \hat j

T = 342.5 \hat i + 675\hat j

Part b)

Net force on Tarzen is given as

F_{net} = T + F_g

F_{net} = 342.5 \hat i + 675\hat j - 849 \hat j

F_{net} = 342.5\hat i - 174\hat j

Part c)

magnitude of the force is given as

F = \sqrt{F_x^2 + F_y^2}

F = \sqrt{342.5^2 + 174^2}

F = 384.2 N

Part d)

Direction of the force is given as

tan\theta = \frac{F_y}{F_x}

tan\theta = \frac{-174}{342.5}

\theta = 333 degree

Part e)

Magnitude of the acceleration

a = \frac{F}{m}

m = \frac{849}{9.81} = 86.5 kg

tex]a = \frac{384.2}{86.5}[/tex]

a = 4.4 m/s^2

Part f)

Direction of acceleration is same as the direction of the force

\theta = 333 degree

lana66690 [7]

hi <3

i believe i explained this answer properly in my last answer but it would be 4kg and 2400m as these are the SI units for these values.

hope this helps :)

Suppose a vector v makes an angle theta with respect to the y axis, what could be the x and y components of the vector v
gtnhenbr [62]

If the angle between the vector and the y-axis is  Θ ,
then the y-component of the vector is

                   (length of the vector) times  cosine( Θ ),

and the x-component of the vector is

                   (length of the vector) times  sine( Θ ) .
