📝 Answered - A worker is being raised in a bucket lift at a constant speed of [tex]$3 ft / s$[/tex]. When the worker's arms are 10 ft off the ground, her coworker throws a measuring tape toward her. The measuring tape is thrown from a height of 6 ft with an initial vertical velocity of [tex]$15 ft / s$[/tex]. Projectile motion formula: [tex]$h=-16 t^2+v t+h_0$[/tex] [tex]$t=$[/tex] time, in seconds, since the measuring tape was thrown [tex]$h=$[/tex] height, in feet, above the ground Which system models this situation? A. [tex]$h=3 t+10$[/tex] and [tex]$h=-16 t^2+15 t+6$[/tex] B. [tex]$10 t +3$[/tex] and [tex]$h =-16 t ^2+6 t +15$[/tex] C. [tex]$-16 t^2+3 t+10$[/tex] and [tex]$h=-16 t^2+15 t+6$[/tex] D. [tex]$-16 t^2+10 t+3$[/tex] and [tex]$h=-16 t^2+6 t+15$[/tex]
