The motion of a human body through space can bemodeled as the motion of a particle at the bodys centerof mass as we will study in Chapter 9. The componentsof the displacement of an athletes center of massfrom the beginning to the end of a certain jump aredescribed by the equationsxf 5 0 1 (11.2 m/s)(cos 18.5)t0.360 m 5 0.840 m 1 111.2 m/s2 1sin 18.582t 2 1219.80 m/s2 2t 2where t is in seconds and is the time at which the athleteends the jump. Identify (a) the athletes positionand (b) his vector velocity at the takeoff point. (c) Howfar did he jump?
