Answer:
10.466
Explanation:
I used pythagorean theorem. It is A^2 + B^2 = C^2 then square root of C^2 to find C which was 10.466.
Explanation:
Its translational kinetic energy is:
KE = ½ mv²
It's rotational kinetic energy is:
RE = ½ Iω²
For a solid sphere, I = ⅖ mr², and since it's not slipping, ω = v/r.
RE = ½ (⅖ mr²) (v/r)²
RE = ⅕ mv²
Therefore, the translational kinetic energy is larger.
Let's first convert the initial and final speed of the vehicle in m/s:
Therefore, the acceleration of the car is given by
And so now we can calculate the force required by using Newton's second law:
Depends on how well built he is probably for the average American 8 MPH
Your being on the moon has no effect on the moon's
gravitational field strength, or on the Earth's for that
matter.
However, YOU notice a change on YOU when YOU move
from one to the other, because of the effect of the gravitational
field strength on you and your internal organs.
If you could stand on the moon, you would experience an incredible
sense of lightness, since the forces of attraction between the moon
and anything else are only 16% as great as the same forces are on
Earth.
