The airplane engine uses oxygen from the air to keep the engines working. Rockets must carry their oxygen for the engines to operate. Third Law of Motion). Rocket propellants by combustion provide the hot gas es that produce reaction force (thrust) when ejected to the rear.
Answer:
The magnitude of the vertical component of its velocity as it hits the ground is 30 m/s. The horizontal distance from the firing point is 750 meters.
Answer:
a)θ=74.03° (N-E)
b)t=1.56 hr
Explanation:
Given that
Plane speed = 200 km/h
Wind speed = 55 km/h
Now from diagram
V is the resultant velocity of plane
V=192.28 km/h towards north
From triangle ABC
θ=74.03°
Given that
d=300 km
We know that
d = V x t
300 = 192.28 x t
t=1.56 hr
