Chapter 11, Problem 11.193RP

A telemetry system is used to quantify kinematic values of a ski jumper immediately before she leaves the ramp. According to the system $r=500$ ft, $\stackrel{.}{r}=-105$ ft/s, $\stackrel{..}{r}=-10$ ft/s², $\theta =25°$ , $\stackrel{.}{\theta }=0.07$ rad/s, and $\stackrel{..}{\theta }=0.06$ rad/s². Determine (a) the velocity of the skier immediately before she leaves the jump, (b) the acceleration of the skier at this instant, (c) the distance of the jump d neglecting lift and air resistance.
