Question

a student carries a bag weighing 5 kg from the ground floor to his class on the first floor that is the work done by the boy is..​

Answer 1

Work done by the boy is 100J

Explanation:

Work performed by force is equivalent to the product of the magnitude of force(F) applied and the distance the body moves through(d).  

Mathematically, Formula for worked done will be given as

W = Fd  ------------(1)

where, F= |F|

Given, mass of a bag, m= 5kg

Displacement, d = 2m

As we know,

F = ma

where,

Force is measured in Newtons, N.

Mass is measured in kilograms, kg.

Acceleration is measured in meters per second square, $m/s^2$

Force, F = m × a =  5 × 10= 50N

Put the value of F in eq(1)

W = 50 X 2 = 100J

Thus, work done by the boy is 100J

2

Force, F = m × a = 5 × 10= 50N

Put the value of F in eq(1)

W = 50 X 2 = 100J

Thus, work done by the boy is 100J
