Question

A child pulls a wagon a distance of 30 m a long athe floor using a rope that makes 30o with the horizontal, how much work does the rope do on the boat if its tension is 200 N

Answer 1

W=5196.15J
As
W=F.d
W=Fdcosθ
where W is work, F is force and d is displacement
Force F= Tension T= 200N
d=30m
Putting values in formula
W=Fdcosθ
W=(200N)*(30m)* cos(30)°
W=(6000Nm)*(0.8660)
W=5196.15Nm=5196.15J
