Answer:
3.125 m
Explanation:
We are given that
Mass of box=m=11.2 kg
Speed of box=u=3.5m/s
Coefficient of kinetic friction=
Final velocity,v=0
a.We have to find the horizontal force applied by worker to maintain the motion.
According to question
Horizontal force=F=

Substitute the values
Horizontal force=
b.According to work-energy theorem






Hence, the box slide before coming to rest=3.125 m
Velocity would be an answer
