ella [17]

Here's the 'vector equation' for that situation:

                  (10N right)  +  (3N left)

               = (10N right)  +  (-3N right)

               =     7N right .

GrogVix [38]

Answer:

95.78125%

18000 m/s

22233.33 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v=u+at\\\Rightarrow v=0+20\times 15\times 60\\\Rightarrow v=18000\ m/s

The velocity of the rocket at the end of the first 15 minutes is 18000 m/s which is the maximum speed of the rocket in the complete journey.

Distance traveled while speeding up

s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=0\times t+\dfrac{1}{2}\times 20\times 900^2\\\Rightarrow s=8100000\ m

Distance traveled while slowing down

s=18000\times 900+\dfrac{1}{2}\times -20\times 900^2\\\Rightarrow s=8100000\ m

Distance traveled during constant speed

384000000-(2\times 8100000)=367800000\ m

Fraction

\dfrac{367800000}{384000000}\times 100=95.78125\ \%

Fraction of the total distance is traveled at constant speed is 95.78125%

Time taken at constant speed

t=\dfrac{367800000}{18000}=20433.33\ s

Total time taken is 900+20433.33+900=22233.33\ s
