Question

Problem 9 You are piloting a rescue plane delivering a botle of Single Malt Scotch to some desperate fisherman in a lake in Northern Quebec. Unfortunately, the lake is fog-bound as you approach it and you must deliver your relief At what horizontal distance, in meters, from the beacon must you drop your package? Assume that the fishermen have placed their beacon in their boat. using the navigation beacon of the fisherman. You check your ground speed and the lowest you can get it to is 105 km/hr and the minimum height from which you can drop the package so that it is safe for you to be able to clear the trees on the other side of the lake is 40.0 m. Suamit Answer Tries 0/6

Explanation / Answer

Given initial Horizontal speed of plane

Vox=105 km/h =105*1000/3600

Vo=29.17 m/s

From

Y=Yo+Voyt-(1/2)gt2

when object hits ground Y=0

0=40+0-(1/2)*9.81*t2

t=sqrt[80/9.81] =2.86 s

Horizontal distance travelled

X=Voxt =29.17*2.86

X=83.3 m
