Question

an aeroplane is moving horizontally with speed 100m/s at height of 2000m from the ground .a small object is detached from it and strikes the ground . calculate the angle from vertical with which it strikes the groun

Answer 1

Answer:

Angle = 45°

Explanation:

An aeroplane is moving horizontally with speed 100m/s at height of 2000m from the ground .a small object is detached from it and strikes the ground . calculate the angle from vertical with which it strikes the groun

Horizontal Speed of object = 100 m/s

S = ut + (1/2)at²

Height = 2000 m

Vertical SPeed = 0

Time taken to reach ground = T

a = g = 10 m/s

2000 = 0 + (1/2)(10)T²

=> T = 20 Sec

Horizontal Distnace Covered = 100 * 20 = 2000 m

Vertical & Horizontal Distance are equal

so Angle = 45°
