1) The weight of the container is 1333 N
2) The mass of the container is 136 kg
Explanation:
1)
The work done in lifting an object is given by:
[tex]W=Fh[/tex]
where
W is the work done
F is the weight of the object (which is equal to the force applied)
h is the vertical distance through which the object has been moved)
In this problem, we have:
W = 3200 J is the work done on the container
h = 2.40 m is the distance through which it has been moved
Solving for F, we find the weight of the container:
[tex]F=\frac{W}{h}=\frac{3200}{2.40}=1333 N[/tex]
2)
The weight of an object is given by
[tex]F=mg[/tex]
where
m is the mass of the object
g is the acceleration of gravity
For the container in this problem, we have
F = 1333 N is the weight
[tex]g=9.8 m/s^2[/tex] is the acceleration of gravity
Solving for m, we find the mass:
[tex]m=\frac{F}{g}=\frac{1333}{9.8}=136 kg[/tex]
