No fixed answer, depends on the surface.
The amount of separation between two horizontal surface/Plane
because the surface of water is horizontal and not vertical.........................
Short answer: should be one-fourth of the distance. Long answer: You can solve with with the equation v^2 = u^2 + 2as We know that the final velocity is zero s = -u^2/2a When we sub in u = 1/2 u, it becomes a quarter of the original displacement. So, it will travel a quarter of the distance.
A gangplank is also known as an inclined plane it is a flat surface whose endpoints are at different heights. By moving an object up an inclined plane rather than completely vertical, the amount of force required is reduced, at the expense of increasing the distance the object must travel. The mechanical advantage of an inclined plane is the ratio of the length of the sloped surface to the height it spans; this may also be expressed as the cosecant of the angle between the plane and the horizontal. Note that due to the conservation of energy, the same amount of mechanical energy is required to lift a given object by a given distance, except for losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
80 jules/20meters= 40Newtons
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.

multiply coefficient of static friction by object mass
It is polarized at 90 degrees to the plane of incidence. If the surface is horizontal, the plane of incidence is vertical & the polarization would be horizontal.
Perpendicular
because the datum surface is perpendicular tothe direction of gravity at any point on it.but the horizontal surface is perpendicular to vertical at one point on it :D
A level is a tool that is placed on a solid surface. There is a string hanging on the level, and if it tilts, the surface isn't an even horizontal surface. If the string doesn't tilt, the surface is even.
A flat surface generally refers to a horizontal surface and is referred to as the plane.
