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, r . = 2105 ft/s, r¨ = 210 ft/s²
, u = 258, u . = 0.07 rad/s, u $ = 0.06 rad/s. 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.
