Question

You have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weight 3,500 N across the carpet to a spot 5 m away on the opposite wall. Hoping to just slide your dresser easily across the floor, you do not empty your clothes out of the drawers before trying to move it. You push with all your might but cannot move the dresser before becoming completely exhausted. How much work do you do on the dresser?
W> 1.75 x 10^4 J
W = 1.75 x 10^4 J
1.75 x 10^4 J > W > 0 J
W = 0 J

Answer 1

Answer:

0.

Explanation:

(A) Work done on the dresser which will be given as :

$W = F d cos \theta$

where, F = weight of the dresser = 3500 N

$d_{expected} = 5m$

However you can move the dresser, that is a real distance,

$d = 0 m$

Substituting,

$W = (0) F(3500)cos (\theta)$ ($\theta$ is the angle at which you apply the force)

$W = 0 J$
