Answer:

From the initial height h

Explanation:

When a material or substance is drop from a height h, it possesses potential energy, immediately it is dropped from that height, the potential energy is gradually converted to kinetic energy, it gets to a point where the potential energy equals the kinetic energy, as the material touches the ground, all potential energy has been converted to kinetic energy already

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1760 1760 × 103 seconds (a
Katen [24]

Answer:

a_c=6.471\frac{m}{s^{2}}

Explanation:

We can calculate the magnitude of the tangential velocity of the moon, using the equation:

v=\frac{2\pi R}{\tau}

(This works, since velocity is defined as distance over time; in this case the distance is 2πR and the time is the period τ)

Next, from the equation of the centripetal acceleration we have:

a_c=\frac{v^{2} }{R}\\\\a_c=\frac{4\pi^{2}R}{\tau^{2} }

Be careful, the radius of the orbit R is equal to the distance from the center of the moon to the center of the planet. So we have to sum the distance from the center of the moon to the surface of the planet and the radius of the planet to obtain R:

R=285.0*10^{6} m+3.50*10^{6} m=288.5*10^{6}m

Finally, plugging the given values into the centripetal acceleration formula, we have:

a_c=\frac{4(3.141)^{2}(288.5*10^{6}m)}{(1760*10^{3}s)^{2}} =6.471\frac{m}{s^{2}}

In words, the moon's radial acceleration a_c is 6.471m/s².

Why the object will not return to its original position?<br>why does the centre of mass fall?​
dusya [7]

Answer:

the object will not return to the original position because it will not have any forces helping it to go up the hill

the center of mass falls since it is going downwards
