Wherever a river loses energy
98J
Explanation:
Given parameters:
Mass of paint can = 5kg
Height of ladder = 2m
Unknown:
Work done = ?
Potential energy = ?
Solution:
Work done in moving the paint is the force applied under gravity to move it through the give height.
Potential energy is the energy due the position of a body at rest.
For this body:
The work done in moving the paint = Potential energy at the top of ladder = m x g x h
m is the mass of the pain can
g is the acceleration due to gravity
h is the height of the building
Input the variables;
Work done = 5 x 9.8 x 2 = 98J
Potential energy = 98J

Energy is the ability to do work.
I think it's D. Usually, to find the volume of an irregularly shaped object, you put it in water with a labeled beaker to measure how much the water rises. The balance would be used to measure the mass in grams.
Since the acceleration is constant, the average velocity is simply the average of the initial and final velocities of the body:
We can proof that the distance covered by the body moving at constant average velocity 
is equal to the distance covered by the body moving at constant acceleration a:
- body moving at constant velocity : distance is given by
- body moving at constant acceleration 
: distance is given by
