A car sits in the parking lot. Above is a cargo plane, flying horizontally at 61 m/s. At the exact moment the plane is 182 m directly above the car, a crate accidentally falls from its cargo doors. Relative to the car, where will the crate land? Enter m as unit and use g = 10. m/s2.
h = Vo*t + 0.5*t^2 = 182 m.
0 + 5t^2 = 182
t^2 = 36.4
t = 6.03 s. = Fall time or time in air.
d = V*t = 61m/s * 6.03s = 367.8 m.
