Question

a man X goes to the top of a building by a vertical spiral staircase. another man Y of same mass goes to the top of building by a slanting ladder . which of the two does more work against gravity and why

Answer 1

angle produce by man goes with ladder will be 90°
work =force*displacement*cos theta
W=F*S*cos90; cos 90=0
W= 0
According to convection the work sone by man by spiral staircase would be more than man ladder.
