<h2>Answer: 9600 J</h2>
The kinetic energy of a body is that energy it possesses due to its movement and is defined as:
Where is the mass of the body and
its velocity
.
This has to do with the speed of an object and how much mass it has; basically how the object is moving.
Now, according to this equation and knowing that the mass of the buffalo is and its velocity
:
Therefore the correct option is B.
Answer:
T1 = 490.5 [N], T2 = 490.5[N]
Explanation:
First, we must draw a free body diagram of the steel ball hanging and the two wires holding it as well as the angle forming the wires between them.
The free-body diagram can be seen in the attached image.
As the cables are symmetrical with respect to the vertical axis, the force in cables 1 and 2 is equal, so when performing a force sum equal to zero on the Y-axis, we can find the force value of any cable.
The solution of the equations can be seen in the attached image
