The last segment of the triple jump tracxk and feild event is the jump, in which the athlete makes a final leap, landing in a sand filled pit. assuming that the velcity of a 185 lb athlete just before landing is 30 ft/s at an angle of 35 degrees with the horizontal and that the athlete comes to a complete stop in .22 seconds after landing, determine the horizontal component of the average impulsive force exerted on his feet during landing?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
