The impulse experienced by a body is equivalent to the body’s change in

Momentum

The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:

On the other hand, the impulse of a constant force is defined as:

We also know that the net force acting on  a particle equals the rate of change  of the particle’s momentum, so:

If the force is constant, then equals the total change in momentum over a period of time:

spectral lines lyman is one set

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
