What the hell is a g? "A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of the loop in which the plane is flying?"

acceleration due to gravity
Need moar then that? What defines a g? Isn't it like, newtons times gravity or something?
9.81 m/(s^2)
32 ft/(s^2)
multiply accordingly
There is a difference between G (capitalized) and g (lowercase). Though this one probably is g, which is just an acceleration due to gravity. There's a way of obtaining it using G (the gravitational constant) in a formula but you can pretty much just accept that it's the numbers that Allie said when you're dealing with things on earth.
Simply put, 4g is 4 times the acceleration due to gravity. Acceleration due to gravity is 9.81 m/s^2
So 4g is 39.24 m/s^2 which is the acceleration on the plane.
Assuming they're talking about earth of course.
This thread makes me sad.
The formula you are looking for is this one, I guess:
F = mv^2 / r
In which:
m = mass
v = speed
r = radius
You can be smart by saying F = m * a = m * 4g = mv^2 / r
You divide out the m and get:
4g = v^2 / r
r = v^2/4g
r = 360000 / 4 * 9.81 =~ 9000 m
