The circus rehearses an idea to spice up the act. When the acrobat steps off, a bunch of plastic flowers will be fired at her out of a cannon, and she will catch the bunch as she falls. The bore of the cannon is at the same height as the trampoline. (a) Choose values for the following. None of them can be 0. i. The distance from the bore of the cannon to the trampoline. 18m ii. The initial velocity of the flowers. This must be high enough to reach the acrobat before she lands. 45 m/s (b) Draw a picture. Label the origin and axes. (c) Create a table showing the information you know for the flowers. (d) Determine the launch angle of the flowers so the acrobat can catch them. (e) Calculate all unknowns about the motion of the flowers. (f) Determine the velocity of the bunch of flowers relative to the acrobat at the time she catches them

i. The distance from the bore of the cannon to the trampoline. 18m
ii. The initial velocity of the flowers. This must be high enough to reach the acrobat before she lands. 45 m/s
(b) Draw a picture. Label the origin and axes.
(c) Create a table showing the information you know for the flowers.
(d) Determine the launch angle of the flowers so the acrobat can catch them.
(e) Calculate all unknowns about the motion of the flowers. (f) Determine the velocity of the bunch of flowers relative to the acrobat at the time she catches them
