<span>C) Both have rocky composition
Explanation
Earth has rocks. Many many rocks.
It is made of many type of rocks such as </span>sedimentary<span>, </span>metamorphic<span>, and </span><span>igneous rocks. and guess what a asteroid is? That is right ! A ROCK.
</span>A asteroid is normally made of <span>stony silicate rocks , but not always , sometimes I can be diamonds!! The point is , they both are rocks floating around space.</span><span>

Answer:
If two forces act on an object in the same direction, the net force is the sum of the two forces. In this case, the net force is always greater than either of the individual forces.
Answer:
a) 3.6 sec
b) 17.7 m/s
c) 17.7 m/s
d) 63.6 m
Explanation:
y = (25sin45)t - 4.9t^2 =17.7t - 4.9t^2
a) to find hang time set y = 0
4.9t^2 = 17.7t or t = 3.6 sec
b) vx = 25cos45 = 17.7 m/s
c) vy = 25sin45 = 17.7 m/s
d) To find the range R, use the results in (a) and (b) into the equation R = vxt:
R = (17.7 m/s)(3.6 sec) = 63.6 m
