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:
420m
Explanation:
Given parameters:
Time = 5minutes
Average speed = 1.4m/s
Unknown:
Distance covered = ?
Solution:
Speed is the rate of change of distance with time.
Mathematically;
Speed =
Distance = speed x time
Insert the parameters and solve;
Convert the time to seconds;
1 minute = 60s
5 minute = 5 x 60 = 300s
So,
Insert the parameters and find the distance;
Distance = 300 x 1.4 = 420m
The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,
Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,
The speed of the wave is 0.5 m/s. Put the values in the formula,
Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
