At what point is its pe a maximum? 1. midway between the highest and lowest points 2. at the highest point 3. at the lowest point 4. the pe does not change.

2. at the highest point

Explanation:

For a generic object, the PE (gravitational potential energy) is defined as

PE = mgh

where

m is the mass of the object

g is the gravitational acceleration

h is the height of the object with respect to the ground

From the formula, we see that PE is maximum when h is maximum: so the PE is maximum when the object is at the highest point.

this could be newton#'s law of cooling. the cooling curve is exponential
