A boy of mass 50kg runs up a set of stairs of total height of 3.0m.find the work done against gravity
Work done= force x displacement.
W = f x s
W = (50 x 10) x 3
W = 1500J
Work done =force ×displacement
W=F×S
=Mg×h =Mgh
W=(50×10)×3.0
W=(500)×3.0
W=1500 Joules.
W= mgh
W= 50×3.0×10
W= 1500J
Very correct it help me in my physics assignment
Very correct
Answer of the question
Work done=forcexdisplacement
W=fxs
W=50x10x3
W=1500J
