The work done in lifting the block is 3430 J
<h3>Calculating work </h3>
From the question, we are to determine the work done in lifting the block
Using the formula,
Work done = mgh
Where m is the mass
g is the acceleration due to gravity
and h is the height
From the question,
m = 50.0 kg
g = 9.81 m/s²
h = 7.00 m
Putting the parameters into the formula,
Work done = 50.0 ×9.8 × 7.00
Work done = 3430 J
Hence, the work done in lifting the block is 3430 J

Answer:
D
Step-by-step explanation:
The measure of x is calculated as
x = 0.5( arc CD - arc BD)
= 0.5(210 - 72) = 0.5 × 138 = 69 → D
