A body of mass 100kg moves with a velocity of 9m/s. Calculate it's kinetic energy
as always, KE = 1/2 mv^2
so plug in your numbers
To calculate the kinetic energy of a moving body, we can use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given:
Mass (m) = 100 kg
Velocity (v) = 9 m/s
Using the equation, we can substitute the values:
KE = 1/2 * 100 kg * (9 m/s)^2
Simplifying the equation:
KE = 1/2 * 100 kg * 81 m^2/s^2
Now we can solve it:
KE = 0.5 * 100 * 81
KE = 0.5 * 8100
KE = 4050 Joules
Therefore, the kinetic energy of the body is 4050 Joules.
To calculate the kinetic energy of a body, you can use the following formula:
Kinetic Energy = (1/2) * mass * velocity^2
Given that the mass of the body is 100 kg and its velocity is 9 m/s, we can substitute these values into the formula:
Kinetic Energy = (1/2) * 100 kg * (9 m/s)^2
First, let's square the velocity:
(9 m/s)^2 = 81 m^2/s^2
Next, we can substitute this value into the formula:
Kinetic Energy = (1/2) * 100 kg * 81 m^2/s^2
Now, we can simplify and calculate the final answer:
Kinetic Energy = 0.5 * 100 kg * 81 m^2/s^2
= 0.5 * 100 kg * 81 m^2/s^2
= 0.5 * 8100 kg m^2/s^2
= 4050 kg m^2/s^2
Therefore, the kinetic energy of the body is 4050 kg m^2/s^2.
