The position of an object at time $t$ is given by the parametric equations \begin{cases} x = 4t^2 + 3t \\ y = 3t^2 + 7 \end{cases} Find the horizontal velocity, the vertical velocity, and the speed at the moment where $t = 1$. Do not worry about units in this problem. Horizontal Velocity = Vertical Velocity = Speed =

Pump Boiler 2 3 Turbine Condenser. 1 P = constant 3 T 2 1 P= constant -5 Basic components and T-s process diagram for an ideal Rankine cycle. An ideal Rankine cycle uses water as a working fluid, which circulates at a rate of 80 kg/s. The boiler pressure is 6 MPa, and the condenser pressure is 10 kPa. The water enters the turbine at 600°C and leaves the condenser as a saturated liquid. Assume that heat is transferred to the working fluid in the boiler from a reservoir at 1400 K and that the fluid in the condenser rejects heat to the surroundings at 25°C. Calculate the following quantities: a. The power required to operate the pump b. The heat-input rate to the water in the boiler c. The power developed by the turbine d. The heat-rejection rate in the condenser e. The thermal efficiency of the cycle

Find the solution of the following initial value problem. 64$y'' - y = 0$ $y(-8) = 1$, $y'(-8) = -1$ $y(t) = \frac{9}{2}e^{-\frac{x}{8}} - \frac{7}{2}e^{\frac{x}{8}}$ The equation $ar^2 + br + c = 0$ is called the characteristic equation for the differential equation $ay'' + by' + cy = 0$. Assuming that the roots of the characteristic equation are real and different, let them be denoted by $r_1$ and $r_2$, where $r_1 \neq r_2$. Then $y_1(t) = e^{r_1t}$ and $y_2(t) = e^{r_2t}$ are two solutions of equation the differential equation. It follows that $y(t) = c_1y_1 + c_2y_2 = c_1e^{r_1t} + c_2e^{r_2t}$.
