During world war 2, there were some cases where the crew fell out of burning aircraft without a parachute and survived the fall. assume that the crew member reached a constant terminal speed of 126.1 km/hr prior to hitting a stack of loose hay. if the crew member can survive an acceleration of 36.0 g, where g is the gravitational constant, and assuming uniform acceleration, how high a stack of hay is required for the crew member to survive the fall?

The crew member can decelerate at a maximum of 36 g. We must convert this into meters per second squared. Moreover, the terminal velocity of the crew member must be expressed in meters per second. These are:

acceleration = 36 * -9.81 = -353.2 m/s² (negative sign due to deceleration)
velocity = 126.1 km/hr = 35 m/s (this will be the initial velocity upon hitting the hay stack)
The final velocity of the crew member will be 0.

We use the formula:

2as = v² - u²
2 * s * -353.2 = 0² - (35²)
s = 1.73 meters

The haystack must be 1.73 meters high

Shania is trying to determine the oldest geologic unit on this map and the reason to why is she unable to do so is that  the units are all the same age.. when there is the same age, there will be no oldest geologic unit and that i cannot be credible.
