He would have landed <em>2x </em> feom the base if his horizontal speed had been double.
That's because the time it takes him to drop from the cliff to the water is the same
in both cases, and the distance feom the base of the cliff to his splash-point is just ...
(his horizontal speed) x (his time falling through the air).

Answer:
2 m/s²
Explanation:
the equations of motion are
S= ut +½at²
v² = u²+ 2as
v = u + at
s = (u+v)/2 × t
From the parameters given
u = 0m/s this is because it starts from rest
Distance (s) = 9m
Time (t) = 3s
Based on this the first equation would be used
s = ut + ½at²
Input values
9 = 0×3 + ½ × a x 3²
9 = 0 + 9a/2
9 = 4.5a
Divide both sides by 4.5
a = 9 / 4.5 m/s²
a = 2 m/s²

Answer:
4.87×10⁶ kJ
1.63×10⁸ Joules
1015 $
Explanation:
a. To convert the units, you can use this conversion factor:
1 kWh = 3.6×10⁶J
1355 kWh . 3.6×10⁶J / 1 kWh = 4.871×10⁹ J
Now we convert to kJ → 4.87×10⁹ J . 1 kJ/1000J = 4.87×10⁶ kJ
b. In 30 days, we used 1355 kWh so, let's determine the use by day
1355 kWh / 30 day = 45.2 kWh
Now we convert the 45.2 kWh to Joules → 45.2 kWh . 3.6×10⁶J / 1 kWh =
1.63×10⁸ Joules
c. We can make a rule of three, for this:
1 kWh costs $0.749
1355 kWh will pay (1355 . 0.749) / 1 = 1015 $
Answer:
A. Kinetic energies are equal.
Explanation:
The kinetic energy of the bodies will be equal since the mass and speed are the same.
Kinetic energy is the energy due to the motion of a body.
Mathematically;
K.E = m v²
m is the mass
v is the speed
The kinetic energy is a scalar quantity with no regard for direction.
