A diner is sitting a horizontal distance d away when this happens. Assume the cork leaves the waiter's hands at the same vertical level as the diner and that the cork falls back to this vertical level when it reaches the diner. Use a Cartesian coordinate system with the origin at the cork's initial position. 50% Part (a) Calcutte the time, ta in seconds, for the cork to reach the diner. borizontally directly toward the waiter opening the diner 50% Part (b) Reacting quickly to avoid being struck, the diner moves 200 m where the champagne bottle. Determine the horizontal distance, din meters, between the person and the diner at the time the cork reaches Summary Grade had previously been sitting. 17% d 5.8743 8T9 HoME per attempt) acoso cotano sinho at ano acota cosh0 tanh0 cotanh0 BACKSPACE oDegrees Radians I give up! for a 25 deduction Feedback current submission.

t = 2 v0 sin theta / g
= (2 * 13.1 * sin 77) / 9.81
t = 2.60 s
b) d = v * t = v0 cos theta * t
= 13.1 * cos 77 * 2.60
d = 7.66 m
