📗 [1 points] Consider a single mass point with mass \(m\) = . Its initial state at \(t\) = \(0\) is \(x_{0}\) = , \(v_{0}\) = , \(F_{0}\) = , where \(x_{0}\), \(v_{0}\), \(F_{0}\) refer to the initial position, velocity, and force. Using the Symplectic Euler method with time step \(\Delta t\) = , the next position is \(x_{1}\) = .

📗 [1 points] Assume a camera's view frustum is defined by (near clipping plane) \(n\) = , (far clipping plane) \(f\) = , (right bound) \(r\) = and (top bound) \(t\) = . Now we have a point \(x\) = in the camera's coordinate system. The Normalized Device Coordinate of this point is NDC = .
