Since 90 degree is 1/4 of a circle, the area will be 1/4 th area of the full circle.

The radius is given by, r = 8 ft, therefore, the area of the full circle is,

\begin{gathered} A=\pi\times r^2 \\ A=3.14\times8^2=200.96ft^2 \end{gathered}

Therefore, the area of the sector is,

A^{\prime}=\frac{1}{4}\times200.96ft^2=50.24ft^2\begin{gathered} A^{\prime}=\frac{\theta}{360}\times\pi\times r^2 \\ \text{ =}\frac{\text{90}}{360}\times\pi\times8^2 \\ \text{ =}\frac{1}{4}\pi\times64=16\pi \end{gathered}

SpyIntel [72]

Answer:

2.88m/s

Step-by-step explanation:

By using the law of conservation of momentum

Initial momentum = final momentum

v = is their combined velocity afterwards

Solving equation (1) for v

V = 2.88 m/s

Therefore the velocity afterward is 2.88 m/s.
