Taking the value of to be .
Let the height above the ground be .Body of mass falls freely from rest a distance of , find the kinetic energy acquired by this body.
Initially , and Gravitational Energy (PE) = .
Due to the conservation of energy, we know that this total of energy stays the same. So at our point 3 metres below the starting point:
Not sure how to work out the KE acquired by the body, and have I written the equations right?
No idea where to start on this one, any help would be greatly appreciated.Part 2: If the particle is brought to rest by a force of , find the further distance fallen.
Thanks again in advance.
