In February 1955, a paratrooper fell 1200 ft from an
-Dominant- [34]

Answer:

s=1.1107\ m is the minimum depth of snow for survivable stopping.

Explanation:

Given:

  • terminal velocity of fall, u=56\ m.s^{-1}
  • mass of the paratrooper, m=85\ kg
  • force on the paratrooper by the ice to stop him, F=1.2\times 10^5\ N

<u>Firstly, we calculate the deceleration caused in the snow:</u>

a=\frac{F}{m}

a=\frac{120000}{85}

a=1411.765\ m.s^{-2}

Now, using equation of motion:

v^2=u^2+2a.s ....................(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)

0^2=56^2+2\times (-1411.765)\times s

s=1.1107\ m

when the elevator is moving upwards but its slowing to a stop at the top floor. what is the direction of the net force on the ri
Zielflug [23.3K]

Answer:Downward

Explanation:

As elevator is moving upward but is decelerating to stop at top

Suppose mg is the weight of man

N is the normal reaction

a is the acceleration

F_{net}=N-mg=m(-a)

here upward direction is positive while downward direction is negative

Therefore net force is in downward direction
