Answer:
The force is 15N
Explanation:
The formula is Force= mass × velocity.
From the question mass is 5kg, velocity is 3m/s.
F= 5×3
F= 15Newton.
Therefore the force is 15N.

Answer:
62.1 ft
Explanation:
We know that
hence 240 gpm will be
From the formula of obtaining efficiency
and making
the subject we have
where Q is flow rate,
is specific weight of water,
is actual head rise and
is the power input to the compressor
Substituting 0.62 for
, 6hp for
,
for
and
for Q then
Therefore, actual head rise of the water being pumped is 62.1 ft
V^2 = vi^2 + 2as
vi = 0 in this case
a = 9.8 m/s^2
So,
V^2 = 2 * 9.8 * 490
v = 98.05 m/s
hope this helps
