A student wants to approximate the amount of work that the force due to gravity does on the student as the student walks up a set of stairs. Which of the following measurements must the student collect in order to approximate the amount of work done by Earth on the student? a. The mass of the student.
b. The angle between the inclined portion of the stairs and the horizontal.
c. The total inclined length of the stairs.
d. The final vertical height above the initial vertical position.

The measurements that the student must collect in order to approximate the amount of work done are:

The amount of work done is contingent upon the amount of Force (which is a product of mass and acceleration) as well as displacement produced in the direction in which the force is applied.

The work done by Earth on the student can be expressed by using the relation:

Therefore, we can conclude that the measurements that the student must collect in order to approximate the amount of work done are:

Options A and D

Explanation:

In this question the student needs to collect these measurements in order to approximate the work done

A. The mass of the student

D. The final vertical height above the initial vertical position.

Workdone = mgh

m = mass

g = gravity = 9.8m/s²

h = vertical height between the initial and the final positions.

The vertical height has to be known as gravity only acts straight down.

we need to know the time interval during which the force acts. impulse of force = momentum change

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
