A telemetry system is used to quantify kinematic values of a ski jumper immediately before she leaves the ramp. According to the system r = 500ft, ̇r = −105ft/sec, ̈r = −10 ft/sec2 , θ = 25◦ , ̇θ = 0.07rad/sec, ̈θ = 0.06rad/sec2 . 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.
In this question, take the value ofg to be 9.81 ms and give your answers to 3 significant figures. 12 An acroplane is ascending in a straight line over a lake, travelling at a constant speed of 225 ms at an angle of elevation of 3°. An aid package is released from the acroplane, and travels a horizontal distance of 1.9 km before landing in the lake. The package is modelled as a particle with initial velocity equal to the...
