Single Stage 0.0/3.0 points (graded) Consider a rocket carrying 100,000 kg of propellant, 10,000 kg of structure, and 5000 kg of payload. What is the propellant fraction of this rocket? Round your answer to at least 2 decimal places (i. e., enter 0.25 to represent 25%) incorrect 1.100 What is the payload fraction of this rocket? Round your answer to at least 2 decimal places. incorrect 0.05 Recall that the relationship between specific impulse and exhaust velocity is: Vex=g0Isp . Assuming that Isp=450s and g0=9.81m/s2 , what is the value of ΔV in m/s that this rocket will produce if all the propellant is consumed in one stage? incorrect 4414

The Propellant fraction is 0.87.

The payload fraction is 0.04.

Δv = 8991.81 m/s

Explanation: To determine the fractions, first, calculate the total mass of the rocket:

The Propellant Fraction will be

0.87

The Payload Fraction is:

0.04

The value of Δv is calculated by the formula:

Δv =

The exhaust velocity () is:

9.81*450

4414.5

is the total mass after the rocket consume all the propellant and is the total mass before the action.

Δv =

Δv =

Δv = - 4414.5.ln(0.13)

Δv = 8991.81

Δv will be 8991.81 m/s.

the answer is b i think

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
