Answer:
The answer is "2 m/s".
Explanation:
The triangle from of the right angle:
![\to (x_c-0.8)+(1.5+y_4) +\sqrt{x_c^2 + 1.5^2}= constant](https://tex.z-dn.net/?f=%5Cto%20%28x_c-0.8%29%2B%281.5%2By_4%29%20%2B%5Csqrt%7Bx_c%5E2%20%2B%201.5%5E2%7D%3D%20constant)
Differentiating the above equation:
![\to V_c +V_A+ \frac{X_cV_c}{\sqrt{x_c^2 +1}}=0\\\\\to 1-V_A+ \frac{0.8 \times 1.5}{\sqrt{ 0.8^2+1.5}}=0\\\\](https://tex.z-dn.net/?f=%5Cto%20V_c%20%2BV_A%2B%20%5Cfrac%7BX_cV_c%7D%7B%5Csqrt%7Bx_c%5E2%20%2B1%7D%7D%3D0%5C%5C%5C%5C%5Cto%201-V_A%2B%20%5Cfrac%7B0.8%20%5Ctimes%201.5%7D%7B%5Csqrt%7B%200.8%5E2%2B1.5%7D%7D%3D0%5C%5C%5C%5C)

![= \frac{1.2}{ 1.46}+1\\\\= \frac{1.2+ 1.46}{ 1.46}\\\\ = \frac{2.66}{1.46}\\\\= 1.82 \ \frac{m}{s}\\\\= 2 \ \frac{m}{s}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1.2%7D%7B%201.46%7D%2B1%5C%5C%5C%5C%3D%20%5Cfrac%7B1.2%2B%201.46%7D%7B%201.46%7D%5C%5C%5C%5C%20%3D%20%5Cfrac%7B2.66%7D%7B1.46%7D%5C%5C%5C%5C%3D%201.82%20%5C%20%5Cfrac%7Bm%7D%7Bs%7D%5C%5C%5C%5C%3D%202%20%5C%20%5Cfrac%7Bm%7D%7Bs%7D)
