Answer:
Initial speed of stone = 12.25 m/s
Explanation:
Given:
Change in distance = 0.15 m
Force applied = 28 N
Find:
Initial speed of stone
Computation:
Using conservation of energy
(1/2)fs² = (1/2)(mv²)
fs² = (mv²)
(28)(0.15)² = (0.028)(v²)
v² = (28)(0.15)²/(0.028)
v = 12.25
Initial speed of stone = 12.25 m/s

Answer is miles sir your welcome it was simple
Answer:
The value is 
Explanation:
From the question we are told that
The molar mass of hydrazine is 
The initial temperature is 
The final temperature is 
The specific heat capacity is ![c_h = 0.099 [kJ/(mol K)] = 0.099 *10^3 J/(mol/K)](https://tex.z-dn.net/?f=c_h%20%20%3D%20%200.099%20%5BkJ%2F%28mol%20K%29%5D%20%3D%200.099%20%2A10%5E3%20J%2F%28mol%2FK%29)
The power available is 
The mass of the fuel is 
Generally the number of moles of hydrazine present is
=> 
=> 
Generally the quantity of heat energy needed is mathematically represented as
=> 
=> 
Generally the time taken is mathematically represented as
=> 
=> t = 2480505.6377 s
Converting to hours
=>
Answer:
Fundamental quantities are quantities that were created to measure a object/substance which are the basis on which derived quantities are formed, where as derived quantities are created by extracting variables from the fundamental quantities.
