A rocket is travelling vertically upwards. Three vertical forces act on it. The thrust acts upwards and is equal to 100 000N. The weight acts downwards and is equal to 80 000N. What is the air resistance

The thrust acts upwards and is equal to 100 000N.
The weight acts downwards and is equal to 80 000N.
What is the air resistance force acting on the rocket when it is travelling upwards at constant
speed?
A 20 000N downwards
B 20 000N upwards
C 180 000N downwards
D 180 000N upwards

The answer is B

If we subtract the upward force from the downward force we will get 20,000

100,000 - 80,000 = 20,000

The answer is b if you see that 100,000 over powers the 80,000 and the biggest number defeats the small number so I’m this case the big number is going up so it with even out 20,000 up
