Two men pull a 31-kg box with forces 9.7 N and 7.6N in the directions shown below. Find the resultant acceleration of the box and the direction in which the box moves.

Explanation:

Given that,

Mass of the box, m = 31 kg

The two forces are shown in the attached figure. They are acting in opposite direction.

Net force, F = 9.7 - 7.6 = 2.1 N

The formula for net force is given by :

F = ma

a is resultant acceleration

So, the resultant acceleration is .

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.
