Question

a waiter carries a tray of food at shoulder length by holding it on his flat palm. as the waiter walks at constant velocity across a ballroom , he does zero work on the tray. explain why this is true using physics principles a waiter carries a tray of food at shoulder length by holding it on his flat palm. as the waiter walks at constant velocity across a ballroom , he does zero work on the tray. explain why this is true using physics principles a waiter carries a tray of food at shoulder length by holding it on his flat palm. as the waiter walks at constant velocity across a ballroom , he does zero work on the tray. explain why this is true using physics principles

Explanation / Answer

workdone, W=F.S


W=F*S*cos(theta)


in the given problem, the angle beween force F and displacement S is 90 degrees


therefore,


W=F*S*cos(90)


W=0
