Description
In classical mechanics, impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction.
<span>Use s = ut + 1/2 at^2, so
s = 0 + 1/2 x20 x 1.8 x 1.8
s = 32.4 m.</span>
In a vacuum they would fall at the same speed, but since it is only off the empire State building, the hammer would fall first
Gravity
Answer:
The Sun looks bigger than other stars because it is so much closer to the Earth. The further away an object is, the smaller it appears, even if it is very big.
Explanation:
However, compared to other stars, our Sun is only a medium-sized star, meaning that some stars are much larger than the Sun and some are much smaller.
Answer:
Pluto
because the the gravitation strength is small, so it will be accelerating slow
