To calculate for the frictional force, we calculate first for the normal force (forcer perpendicular to the surface)
Fn = (2,493 kg) (9.8 m/s²) = 24243.51 N
Then, we multiply this value with the frictional constant which is not given in this problem. If the frictional coefficient is equal to x then, the frictional force is equal to 24243.51x.
That's true.
Radiation always carries energy.
An object at 0 K doesn't have any.
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

Answer:
The distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
Explanation:
We have the average distance across the Atlantic ocean, 
the average distance to the moon, 
The factor by which the distance to moon is greater than the width of Atlantic ocean:
i.e.
the distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
