velocity of the conveyor belt if the boxes leave the incline at B with a velocity of Baits. 2.. The last segment of the triple Jump track- -and-field event is the Jump, in which the
athlete makes a final leap, landing in a sand- filled pit. Assuming that the velocity of a
84kg athlete just before lending is 9.141111% at an angle of 35° with the horizontal and that
the athlete comes to rest to a complete stop in l]. 223 after landing, determine the horizontal component“ of the iaflerage impulsive force excited on his feet dpnng landing
