Question

At the bottom of a loop in the vertical plane, an airplane has a horizontal velocity of 335 mi/h and is speeding up at a rate of 10 ft/s-.The radius

of curvature of the loop is 1 mi. The plane is being tracked by radar at O. What are the recorded values of r, r, 0, and 0for this instant? \text { The recorded value of } \dot{r} \text { is } \square \mathrm{ft} / \mathrm{s} \text {. } \text { The recorded value of } \ddot{r} \text { is } \square \mathrm{ft} / \mathrm{s}^{2} \text {. } \text { The recorded value of } \dot{\theta} \text { is }-\square \mathrm{rad} / \mathrm{s} \text {. } \begin{array}{l} \text { The recorded value of } \ddot{\theta} \text { is }\\ \mathrm{rad} / \mathrm{s}^{2} \end{array}
