Question

a student carries a bag weighing 5 kg from the ground floor to his class on the first floor which is 2m high. the work done by the body is​

Answer 1

Answer:

1. work done will be 10 newton
2. coz workdone=mass×distance
3. w=m×s
4. that's why w=5×2=10N

Answer 2

Answer:

100J

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

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

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 asW = Fd -----(1)

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 asW = Fd -----(1)where, F= |F|

Given, mass of a bag, m= 5kg

Given, mass of a bag, m= 5kgDisplacement, d = 2m

Given, mass of a bag, m= 5kgDisplacement, d = 2mAs we know

F = ma

F = mawhere Force is measured in Newtons, N.

Force is measured in Newtons, N.Mass is measured in kilograms, kg.

Force is measured in Newtons, N.Mass is measured in kilograms, kg.Acceleration is measured in meters per second square, m/s^2m/s

Force, F = m × a = 5 × 10= 50N

Force, F = m × a = 5 × 10= 50NPut the value of F in eq(1)

Force, F = m × a = 5 × 10= 50NPut the value of F in eq(1)W = 50 X 2 = 100J

Force, F = m × a = 5 × 10= 50NPut the value of F in eq(1)W = 50 X 2 = 100JThus, work done by the boy is 100J
