Question

the speed of an air plane is 600 km/h & the airplane is flying at the height of 1000 m.calculate that from how many hours the airplane is flying​

Answer 1

Answer:

The height = 1000 m

From the formula

$h = \frac{1}{2} g {t}^{2}$

$t = \sqrt{ \frac{2h}{g} } = \sqrt{ \frac{2000}{9.8} }$

t = 14.2828569 sec

Horizontal distance

$= v.t$

= 2,380.46667 m

= 2.38 km

Answer 2
