Aparachutist descending at a speed of 14.8 m/s loses a shoe at an altitude of 55.1 m. what is the speed of the shoe just before it hits the ground? the acceleration due to gravity is 9.81 m/s 2 . answer in units of m/s.

v = 36.05 m/s

Explanation:

It is given that,

Initial speed of the parachutist, u = 14.8 m/s

Altitude, h = 55.1 m

The acceleration due to gravity,

Let v is the speed of the shoe just before it hits the ground. The third equation of motion is given by :

v = 36.05 m/s

So, the speed of the show just before it hits the ground is 36.05 m/s. Hence, this is the required solution.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
