The equation for determining the kinetic energy of the system is,
KE = 0.5mv²
where m is the mass, v is velocity and KE is the kinetic energy. When both objects have the same mass, and velocity but different direction, they will have the same kinetic energy.
This is because the exponent in the velocity is squared cancelling out the effect of the sign appearing before the number.
Answer: 115.38N
Explanation:
Firstly, let's determine the constant.
Hooke's law was discovered by Robert Hooke in 1660.
Using hooke's law which states that provided the elastic limit of an elastic material is not exceeded, the force is equal to the extension applied provided all factors are kept constant.
Hooke's Law is a principle of physics that states that the force which is needed to extend or compress a spring by some distance is proportional to that distance
Therefore,
Force=kx
K= F/x
Where Force= 75m
x= 0.065m
K= 75/0.065m
K= 1153. 846N
We can use the constant to find the force when the distance that is stretched(x) is known.
Here
Force=kx
F= 1153.846 × 0.10
F= 115.38N
The force required to stretch it by this amount is 115.38N.
The three things that are necessary are power, a force, and movement in the opposite direction of the applied force.
A force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
There is a covalent bond formed between two atoms that do not easily lose electrons.
hope this helps :)
