The length of nylon rope from which a mountain climber is suspended has a force constant of 1.40×10^{4} 4 n/m . (a) what is the frequency at which he bounces, given his mass plus and the mass of his equipment are 90.0 kg? (b) how much would this rope stretch to break the climber's fall if he free- falls 2.00 m before the rope runs out of slack? hint: use conservation of energy.

Part a)

Part b)

Explanation:

Part a)

as we know that frequency of oscillation of the object connected to elastic rope is given as

now we have

m = 90 kg

now from above equation

Part b)

If the climber falls freely till L = 2 m before rope start to stretch

then to find the maximum stretch we will have

by solving above equation we have

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.

truck y has a greater velocity than truck x.
