Let us assume that rocket only runs in initial energy and not using its own to flying.
Also , let upward direction is +ve and downward direction is -ve .
Initial velocity , u = 58.8 m/s .
Acceleration due to gravity , 
.
Final velocity , v - = 0 m/s .
We know , by equation of motion .
Hence, this is the required solution .
Answer:
Explanation:
Given
Force 
time interval 
Impulse is given by 
For two significant Figure
If you look on the periodic table you will see the top group elements depending on how the elements relate to each in the column. All of the elements in that column show they all have 1 electron in their valence shell. Some of the chemicals in that family or group are Sodium, Lithium, Potassium. The are very reactive because they only have one electron and what 7 more to become stable.
