Gravitational potential energy = mass x gravity x height
gpe = mgh
solve for m =
solve for g =
solve for h=
what is the answer

Explanation:

The mathematical expression for the gravitational potential energy (GPE) is given by :

Where

m is the mass of an object

g is the acceleration due to gravity

h is the height

(a) Solve for m :

(b) Solve for g :

(c) Solve for h :

Hence, this is the required solution.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

answer; how far out of place which the object finished relative to the starting location;
