Answer 2

Answer:

Correct answer is 100 J

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).  

W = F*d....(1)

Given, mass of a bag, m= 5 kg

Displacement, d = 2 m

As we know,

F = ma....

Force = m × g= 5×10= 50 N

W = 50 × 2 = 100 J

hope it helps..
