<u>Answer:</u>
1130400 km
<u>Step-by-step explanation:</u>
We know the formula for circumference of a circle:
<em>Circumference =
</em>
So we need the radius of Saturn ring to calculate its circumference.
We are given Saturn's diamter which is 120,000km; and know that Saturn's ring extends for about 120,000 km from the circumference of the Saturn.
Therefore, the radius of Saturn's ring will be 120000 km plus half of the diameter of Saturn:
Radius of Saturn's ring = 120000 + (120000/2) = 180000 km
Circumference of Saturn's rings = 2 x 3.14 x 180000 = 1130400 km
Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.
KE = 0.5 x mv^2
M (mass) = 54kg
V (velocity) = 15m/s^2
Then, we plug the values in.
KE = 0.5 x 54(15^2)
Now, we solve.
KE = 0.5 x 54(225)
KE = 0.5 x 12150
KE = 6075
Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.
Thus, the kinetic energy of the object is 6,075J.
