Two forces, one four times as large as the other, pull in the same direction on a 10kg mass and impart to it an acceleration of 2.5 m/s2. If the smaller force is removed, what is the acceleration of the mass?

The acceleration of the mass is 2 meters per square second.

Explanation:

By Newton's second law, we know that force (), measured in newtons, is the product of mass (), measured in kilograms, and net acceleration (), measured in meters per square second. That is:

(1)

The initial force applied in the mass is:

In addition, we know that force is directly proportional to acceleration. If the smaller force is removed, then the initial force is reduced to of the initial force. The acceleration of the mass is:

The acceleration of the mass is 2 meters per square second.

mass and volume are the answers you are looking for

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
