How do i calculate the kinetic energy
1 answer:
The kinetic energy is found at 150 J. The work-energy theorem is applied in the given equation.
<h3>What is Kinetic energy?</h3>The energy possessed by the body by the virtue of motion is known as Kinetic energy. It is found as the product of mass and the square of the velocity.
The given data in the problem is;
The mass is, m=0.15 kg
Force, F=300 N
Distance,d=0.50 m
From the work-energy theorem, kinetic energy is equal to the work done.
Work done = Kinetic energy
Hence, kinetic energy is found at 150 J.

Answer:
-2.5 m/s²
Explanation:
The acceleration of a body is the change in it's velocity with time.
The change in velocity with time can be obtained as the slope of a velocity time graph ;
Acceleration = (change in velocity / change in time)
Taking the slope :
Change in Velocity = △y = y2 - y1
Change in time = △x = x2 - x1
(10, 15) ; (0, 40)
△y / △x = y2 - y1 / x2 - x1 = (40 - 15) / (0 - 10)
△y / △x = 25 / - 10 = - 2.5 m/s²
Answer:
1178 nm
Explanation:
We are given that
Wavelength of light=
We have to find the thickness of spacer if five dark fringes are observed between the edges of the glass.
Suppose that first dark fringe and fifth dark fringe near spacer, then the path length of light is 4 times the wavelength of light.
The light passes through air film is two times then the change in air film thickness from one edge to other is two times the wavelength of light.
Change in air film thickness from one edge to other edge is same as the thickness of spacer.
Therefore, thickness of spacer=
Thickness of spacer=m
Thickness of spacer=1178 nm
Hence, the thickness of spacer=1178 nm
