A body of mass 15 kg moving with a uniform velocity 4 ms -1 what is it kentic energy
What is 1/2 * massInKg*Velocity^2
To calculate the kinetic energy of an object, you can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
In this case, the mass of the body is 15 kg and the velocity is 4 m/s.
Plugging these values into the formula, we have:
Kinetic Energy = (1/2) * 15 kg * (4 m/s)^2
First, let's calculate the square of the velocity:
(4 m/s)^2 = 16 m^2/s^2
Now, let's substitute this value back into the formula:
Kinetic Energy = (1/2) * 15 kg * 16 m^2/s^2
Simplifying further:
Kinetic Energy = 120 kg m^2/s^2
The unit of kinetic energy is Joules (J), so the final answer is:
Kinetic Energy = 120 J
