Answer:
The pilot must be began at an altitude of 826.53 m to avoid crash into the sea.
Explanation:
Given that,
Velocity = 270 m/s
Acceleration = 9.0g s
We need to calculate the altitude
Using formula of centripetal acceleration


Where, v = velocity
r = altitude
a = acceleration
Put the value into the formula


Hence, The pilot must be began at an altitude of 826.53 m to avoid crash into the sea.
I have all the answers here so take this
Force is the interaction that changes the motion of an object. If we want to make a jump, our legs have to exert a force to the ground (or launch points), so that we can gain an equal and opposite force that changes our motion from being static on the ground to moving forward.
The correct answer is all of the above. In a nuclear reactor, the moderator is usually made of graphite, placed between the fuel rods, and used to slow down neutrons. The nuclear moderator is a medium in which reduces the speed of the fast neutrons.
