For a parallelogram with 2 sides at right angles to the other two sides, then with WS =10 and then SZ would equal WS length so SZ = 10 also but SZ=2x-6 so 2x-6=10 and solving for x = 8. That is the answer either if the sides are perpendicular or if WS and SZ are part of the same diagonal.
Assuming the radius is 5.4m. The exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.
<h3>Length of an arc</h3>
Arc length of the circle=(theta)/360×pi×diameter
Diameter=2×radius
Where:
radius=5.4
Diameter=2×5.4=10.8
theta=60°
Arc length:
Arc length=60°/360°×π×10.8
Arc length=5.6548667765 or 1.8π
Inconclusion the exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

Answer:
initial velocity: 0.0 m/s, acceleration is 1.75 m/s/s or m/s^2
Explanation:
Ball begins at rest; change in velocity/change in time (7-0/4-0) is acceleration
