Answer:
8 hp
Explanation:
Power = work / time
P = W/t
Work = force × distance
W = Fd
Substituting:
P = Fd/t
P = Fv
Given that F = 300 N and v = 20 m/s:
P = (300 N) (20 m/s)
P = 6000 W
P = 6 kW
Converting to horse power:
6 kW × (1 hp / ¾ kW) = 8 hp
Answer:
in projectile motion at maximum height v = 0
we can use the suvat equation to find v(initial)
since in this case v(final) is 0
t = 2.4 seconds
we need to find v(initial) or u
v = u+at
u = v- at
in this case a = g (gravity) = -9.81
u = 0 - (-9.81 * 2.4)
u = 9.81 * 2.4
the negatives become positive sin it’s a double negative ( - - = +)
The moon phase shows that D. light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
<h3>What is a moon phase?</h3>
It should be noted that the <em>moon</em> phase simply means the portion of the moon that we can see from the Earth.
In this case, the light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
