$a =6.3 m/s^2$ $t = .44s$

Work Step by Step

Both your sister and the turkey will begin accelerating at mg, where m is her mass. This means that the acceleration is given by: $ a = \frac{F}{m}=\frac{12*9.8N}{12+6.8 kg}=6.3 m/s^2$ The table is .60 m long, so the time you have is given by: $ x = x_0+v_0t+1/2at^2$ $t = \sqrt{\frac{2x}{a}}=\fbox{.44s}$
