There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target. Part A A pilot flying low and slow drops a weight; it takes 3.4 s to hit the ground, during which it travels a horizontal distance of 120 m. Now the pilot does a run at the same height but twice the speed. How much time does it take the weight to hit the ground? Express your answer with the appropriate units. tt = nothing nothing

Geovanni Mclean · Answer 1

A pilot flying a weight; it takes t = 3.4 s to hit the ground, during which it travels a horizontal distance d = 120 m

h = g/2*t^2

h = 4.903*3.4^2

h=56.701 m

V = d/t

V = 120/3.4

V=35.3 m/sec

Now the pilot does a run at the same height but twice the speed.

How much time (t1) does it take the weight to hit the ground?

t1 = t = 3.4 sec (depending just upon height)
