In february 1955, a paratrooper fell 1200 ft from an
airplanewithout being able to open his chute but happened to land
in snow, suffering only minor injuries. assume that his speed at
impact was56 m/s (terminal speed0, that his mass (including gear)
was 85 kg, and that the force on him from the snow was at the
survivable limitof 1.2 x 10 ^ 5 n. what is the minimum depth of
snow that wouldhave stopped him safely?

is the minimum depth of snow for survivable stopping.

Explanation:

Given:

Firstly, we calculate the deceleration caused in the snow:

Now, using equation of motion:

....................(1)

where:

v = final velocity of the body after stopping

u = initial velocity of the body just before hitting the snow

a = acceleration of the body in the snow

s = distance through in the snow

Putting respective values in eq. (1)

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
