Solution

Dear Student,

$w o r k = f o r c e \times d i s p l a c e m e n t$

In both situations, men are applying force but when moving up the incline there is displacement. But when man is moving on frictionless horizontal surface displacement is zero.

So, man moving up is doing work.

Regards,
