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.
Electrons carry a negative charge.
Answer:
4000 J
Explanation:
W = F = 2000N , s = 20 m
Workdone = F × s = 200 × 20 = 4000J
