A cube slides down the surface of a ramp at a constant velocity. What is the magnitude of the frictional force that acts on the cube due to the surface?

The component of weight of the cube parallel to the plane

Explanation:

From the question we are told that

Cube slides at constant speed

Generally the equation for frictional force is given by

where

Generally the equation fo Normal force is mathematically given as

Therefore

Generally at constant velocity frictional force f will be

Therefore

The magnitude of the frictional force that acts on the cube due to the surface is the component of weight of the cube parallel to the plane

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

a.) travels faster in solids because the particles are closer together.
