Equations of motion (EoM) use EoM <span>v2=u2+2ax</span> to establish velocities at positions shown in blue in drawing from EoM v=u+at for final 1 second of flight time, we can say v=u+g(1) <span><span>2gH−−−−√</span>=<span><span>2g1625H</span>−−−−−−√</span>+g</span><span> then, solve for H [in terms of g]

Answer:
18 m/s
Explanation:
Given that,
Speed of river is 8 m/s due South
From the shore, you see a boat moving South with a speed of 10 m/s. Both boat and river are moving in same direction. The resultant velocity will add up.
v = 10 m/s + 8 m/s
v = 18 m/s
Hence, the rowers are moving with a speed of 18 m/s.
Well when you eat you get energy and then you use it to ride up the hill sorry I don't know how it is classified
Answer:
Water that contains a larger than normal amount of <em>magnesium</em> is still safe to drink.
Explanation:
Sulfur, lead and arsenic are harmful metals that are toxic to human health. Although magnesium present at high concentrations (above approximately 250 mg/l each) can have a laxative effect. However, data suggest that consumers adapt to these levels as exposures continue.
Pretty sneaky, I must say !
Work = (force) x (distance)
That formula says nothing about the directions of the force OR
the distance. As long as they're both in the same direction, they
can both be horizontal (sliding a crate on the floor), vertical (lifting
something), or on any slant in between.
Roger's force and distance are both in the same direction ... the
direction of the incline ... so
Work = (60 newtons) x (10 meters) = 600 joules.
