Answer:
143
Explanation:
Using one of the 3 fundamental equations in physics, y=vo*t+1/2gt^2, we can use this equation to find the total distance that was traveled.
Acceleration due to gravity is always 9.8m/s^2 and time is 5.4s, we also have no initial velocity.
Given this, we can plug in the known variables.
y=0t+1/2*9.8*5^2
simplify,
y=4.9*5.4^2
y=4.9*29.16
y=142.884m which we can round up to 143 meters
Final Answer: 143 meters
Answer:
-10
Explanation:
The rectangular area is the base bbb times height hhh.
\begin{aligned}\Delta x&= A \\\\ &=(2\,\text s)\left (-5\,\dfrac{\text m}{\text s}\right ) \\\\ &= -10\,\text m\end{aligned}

its correct no need to change anything :))
Answer:
T = 34.54 N
Explanation:
First we find the buoyant force acting on the sphere, due to displaced water. For that purpose, we need to find the volume of water displaced by the sphere.
Volume of Water Displaced = V = (Mass of Sphere)/(Density of metal)
V = 4.7 kg/(4000 kg/m³)
V = 0.001175 m³
Now, the buoyant force is given as:
F = (Density of Water)(V)(g)
F = (1000 kg/m³)(0.001175 m³)(9.8 m/s²)
F = 11.52 N
Now, we find the weight of the sphere:
W = mg = (4.7 kg)(9.8 m/s²)
W = 46.06 N
Since, both the tension force (T) and buoyant force act in upward direction, while the weight of sphere act in downward direction. Therefore,
W = T + F
T = W - F
T = 46.06 N - 11.52 N
<u>T = 34.54 N</u>
