Abox weighing 58 n sits at rest on an inclined plane. the plane is angled 34 degrees from the horizontal. what is the mass of the box

5.9 kg

Explanation:

The weight of an object is given by:

where

m is the mass of the object

g = 9.8 m/s^2 is the gravitational acceleration

In this problem, we have a box with a weight of W = 58 N. Therefore, we can re-arrange the equation above using this number to find m, the mass of the box:

The fact the box is on an inclined plane is totally irrelevant for the resolution of the problem.

a coal burning power plant

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
