Answer to Question #174923 in Mechanics | Relativity for Prince Ofori

Question

An object is to be dropped from an aeroplane so as to hit a target on the ground. If the aeroplane is travelling horizontally at 80m/s at a height of 2000m, calculate the position of the aeroplane when the object is released. And the time for the object to hit target from the target from the instant of release.

Answer 1

Answer

By second equation of motion in vertical direction

$s=u_yt+\frac{1}{2}gt^2$

Initially $u_y=0m/s$

$2000=9.8t^2\\t=14.28seconds$
