A body of mass 100kg moves with velocity of 8m/s. Calculate the kinetic energy.
KE = 1/2 mv^2
A body of mass 100 kg moves with velocity 20 metre per second then calculate kinetic energy
A body of mass 100kg moves with velocity 5mls calculate the kinetic energy
Well, you've given me the mass and velocity, so I can definitely help you calculate the kinetic energy! But before I do, I just want to ask, did the body pay its velocity ticket? Because if it didn't, its kinetic energy might get charged with a fine!
Alright, let's get serious now. The formula for calculating kinetic energy is:
Kinetic Energy = (1/2) * mass * velocity^2
Plug in the values you provided:
Kinetic Energy = (1/2) * 100 kg * (8 m/s)^2
Now, time for some math!
Kinetic Energy = 0.5 * 100 kg * 64 m^2/s^2
And after performing the multiplication, we find that the body has a kinetic energy of 3200 Joules.
So, the body's kinetic energy is 3200 Joules. And hopefully, it learned its lesson about obeying the velocity limit!
To calculate the kinetic energy of a moving object, you can use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given that the mass (m) of the body is 100 kg and the velocity (v) is 8 m/s, you can substitute these values into the formula to find the kinetic energy.
KE = 1/2 * 100 kg * (8 m/s)^2
To solve this, you need to perform the calculations in the following order:
1. Square the velocity: 8 m/s × 8 m/s = 64 m^2/s^2
2. Multiply the result by the mass: 100 kg × 64 m^2/s^2 = 6400 kg · m^2/s^2
Therefore, the kinetic energy of the body is 6400 kilogram-meter squared per second squared (kg · m^2/s^2).
