What is the velocity of an object of mass 1kg which had 200j of kinetic energy

1 answer

The velocity of an object can be calculated using the equation:

Kinetic Energy = (1/2) * mass * velocity^2

Given that the mass is 1kg and the kinetic energy is 200J, we can rearrange the equation to solve for velocity:

200J = (1/2) * 1kg * velocity^2

Dividing both sides of the equation by (1/2) * 1kg:

400J/kg = velocity^2

Taking the square root of both sides of the equation:

velocity = √400J/kg = 20m/s

Therefore, the velocity of the object is 20 m/s.
