The kinetic energy of the block when it reaches the bottom is 39.2 J.
<h3>
Kinetic energy of the block at the bottom</h3>
Apply the principle of conservation of energy.
K.E(bottom) = P.E(top)
P.E(top) = mgh
where;
- m is mass of the block
- g is acceleration due to gravity
- h is the vertical height of fall
P.E(top) = 5 x 9.8 x 0.8
P.E(top) = K.E(bottom) = 39.2 J

The last one. Opposites attract while similar ones repulse each other so all forces are pushing them apart
Answer: the relationship between the input force and output force is that, Input Force represents the amount of force that you put into another object (which is considered as the load force) while Output Force represents the force that a specific object has as a result of the input force.
Explanation:
Using a lever as an example, a broom is a lever used to sweep floors, the input force is applied by one of the arm used in sweeping, while the output force is on the other edge of the broom (broom tip)
Answer:
Total energy =kinetic energy +potential energy.
