Question

calculate the work of coolie when a coolie of height 1.5m walks with a suitcase of 50 kg on his head for 100m
Please answer it fast​

Answer 1

Answer:

0 N

Explanation:

because direction and force applied is perpendicular to each other.

W= F*s*cos(∆) where ∆ is the angle between force and direction.

Here ∆=90° so

W=F*s*cos(90°)= F*s*0 = 0N

● The work done will be zero because a coolie carries a load make an angle of 90 degree wherever the 90 degree created the work done will be zero.

Proof:

W = FS Cos Q

W = FS Cos (90°)

W = FS (0)

W = 0
