Given,
Mass of suitcase= 20kg
Height the suitcase is lifted up= 2m
so,
work done= mass*acc. due to gravity*height
= 20*10*2
=400J/400Nm
Hope it helps!!

Hii friend,

We know the formula,

Work done= force × distance

Force= mass ×acceleration

Work done= mass ×acceleration× distance

work done= 20×10×2

Work done= 400 kg m²/s².

How this helps you a little!!!
