Question

3. Imagine a 10kg block moving with a speed of 20m/s

calculate the kinetic energy of this block

Answer 1

The formula of the kinetic energy is:

`E_(k) = (m v^(2) )/(2)`
where m is a mass of the object, v is speed of the object at the moment of time. So we have:

`E_(k) = (10* 20^(2) )/(2) = 2000J`
The answer is 2000 Joules.
