Answer:
The weight of the brick is 300 lb.
Explanation:
Given that,
The work done in lifting a load of bricks = 15000 ft lb
It is lifted to a height of 50 ft
We need to find the weight of the brick. The work done by an object is given by :
[tex]W=F\times d[/tex]
Here, F = W (weight of the bricks)
[tex]F=\dfrac{W}{d}\\\\F=\dfrac{15000\ ft-lb}{50\ ft}\\\\F=300\ lb[/tex]
So, the weight of the brick is 300 lb.
The weight of the brick will be "300 lb".
Given:
Work done,
Height,
As we know the formula,
→ [tex]W = F\times d[/tex]
or,
→ [tex]F = \frac{W}{d}[/tex]
By substituting the values, we get
→ [tex]= \frac{15000}{50}[/tex]
→ [tex]= 300 \ lb[/tex]
Thus the response above is right.
