Small-plane pilots regularly compete in "message drop" competitions, dropping heavy weights (for which air resistance can be ign
iren [92.7K]

plane is flying at an altitude of 70 m

now if an object is dropped from it then time taken by object to drop on ground will be given as

y = v_i* t + \frac{1}{2}at^2

here initial speed in vertical direction must be zero as plane is moving horizontal

given that

y = 70 m

a = 9.8 m/s^2

70 = 0 + \frac{1}{2}*9.8*t^2

t = 3.77 s

now since the plane is moving horizontally with speed v = 44 m/s

so the horizontal distance moved by the object will be

d = v_x * t

d = 44 * 3.77

d = 166.3 m

so the distance moved by the box is 166.3 m
