A Body with a mass of 150kg is located at a height of 45 m. If allowed to fell freely to the ground. What will be its velocity on impact?
3375* v^2= 66217.5
Is this done correctly?
There are a lot more steps than you need.
V = sqrt(2 g h)
Forget about the mass.
I do not agree with your V^2 number. You have 45 meter height terms on both sides of your equation. That is wrong.
