A person throws a ball upward with an initial speed of 15 m/s, and then a second (identical ball) with an initial speed of 30 m/s. How much higher up is the maximum height of the second ball, compared to that of the first ball? Show Hint The second ball's maximum height is twice as high. The second ball's maximum height is less than twice as high. The second ball's maximum height is more than twice as high.

Find the parametrization for the line segment joining the points P(0,1,2) and Q(0, -1,2). Draw coordinate axes and sketch the segment, indicating the direction of increasing t for the parametrization. Find the parametrization for the line segment joining the two points. Use P(0,1,2) as the base point and $\overrightarrow{PQ}$ as the vector. Let y = 1 - 2t. x = , y = , z = , $0 \le t \le$ (Type expressions using t as the variable.) Choose the sketch below which shows the correct coordinate axes and line segment and indicates the direction of increasing t for the parametrization. ? ?.

Chapter 8 Operational Amplifiers Assumptions: Assume a supply voltage-limited op-amp. The initial condition is $v_{out}(0) = 0$. Analysis: For an ideal op-amp integrator the output would be $$v_{out}(t) = -\frac{1}{R_s C_f} \int_{-\infty}^{t} v_s(t')dt' = -\frac{1}{0.2} \int_{-\infty}^{t} [0.5 + 0.3\cos(10t')]dt'$$ $$= -2.5t + 1.5\sin(10t)$$ However, the supply voltage is limited to $\pm 15$ V, and the integrator output voltage will therefore saturate at the lower supply voltage value of $-15$ V as the term $2.5t$ increases with time. Figure 8.46 depicts the output voltage waveform. Comments: Note that the DC offset in the waveform causes the integrator output voltage to increase linearly with time. The presence of even a very small DC offset will always cause integrator saturation. One solution to this problem is to include a large feedback resistor in parallel with the capacitor; this solution is explored in the homework problems. CHECK YOUR UNDERSTANDING How long will it take (approximately) for the integrator of Example 8.12 to saturate if the input signal has a 0.1-V DC bias [that is, $v_s(t) = 0.1 + 0.3\cos(10t)$]?
