To solve this, we are going to use the formula for the kinetic energy of an object: $E_{k}= \frac{1}{2} mv^2$
where
$E_{k}$ is the kinetic energy of the object.
$m$ is the mass of the object.
$v$ is the speed of the object.

We know form our problem that the mass of the horse is 500 kilograms, so $m=500$ ; we also know that the speed of the horse is 5 meter/second, so $m=5$ . Lets replace those values in our formula to find $E_{k}$ :
$E_{k}= \frac{1}{2} mv^2$
$E_{k}= \frac{1}{2} (500)(5)^2$
$E_{k}= \frac{1}{2} (500)(25)$
$E_{k}= \frac{12500}{2}$
$E_{k}=6250$ J

We can conclude that the kinetic energy of the horse is 6250 Joules.

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes the

leonid [27]

Answer:

$KE_A=33\ J$

$KE_B=99\ J$

Explanation:

Given:

Let mass of the particle B be, $m_B=m$

then the mass of particle A, $m_A=3m$

Energy stored in the compressed spring, $E=132\ J$

Now when the compression of the particles with the spring is released, the spring potential energy must get converted into the kinetic energy of the particles and their momentum must be conserved.

Kinetic energy:

$\frac{1}{2}m_A.v_A^2+\frac{1}{2}m_B.v_B^2=132$

$3m.v_A^2+m.v_B^2=264$ .............................(1)

Using the conservation of linear momentum:

$m_A.v_A+m_B.v_B=0$

$3m.v_A+m.v_B=0$ .............................(2)

Put the value of $v_A$ from eq. (2) into eq. (1)

$3m\times (\frac{-v_B}{3})^2+m.v_B^2=264$

$v_B^2=\frac{198}{m}$ ...........................(3)

Now the kinetic energy of particle B:

$KE_B=\frac{1}{2}\times m_B\times v_B^2$

$KE_B=\frac{1}{2}\times m\times \frac{198}{m}$

$KE_B=99\ J$

Put the value of $v_B^2$ form eq. (3) into eq. (1):

$v_A^2=\frac{22}{m}$

Now the kinetic energy of particle A:

$KE_A=\frac{1}{2}m_A.v_A^2$

$KE_B=\frac{1}{2}\times 3m\times \frac{22}{m}$

$KE_A=33\ J$

Why do you think that it’s fairly easy for the sun to fuse hydrogen atoms, but a lot harder to fuse helium atoms?

liq [111]

Answer: Because it involves a process called the proton-proton chain.

Explanation:

Two protons (hydrogen-1) fuse together, producing deuterium (hydrogen-2) and other particles plus energy,Deuterium (hydrogen-2) and a proton (hydrogen-1) fuse, producing helium-3 and energy,Two helium-3 nuclei fuse together, producing helium-4, two protons (hydrogen-1), and energy,Helium-3 fuses with helium-4, producing beryllium-7, which decays and then fuses with another proton (hydrogen-1) to yield two helium-4 nuclei plus energy
