Question

The exhaust gases from a rocket provide a thrust of 90000000N at lift off.
The mass of the rocket is 3000000kg.
a) Calculate the weight of the rocket on Earth.
b) i) Use arrows to label the weight and thrust in the
appropriate places on this diagram of a rocket.
ii) Calculate the resultant force on the rocket at lift off.

Answer 1

Can you remind me of the Formula?

Answer 2

F=ma?

Answer 3

n=kgm/s^2

Answer 4

Oh is that it?

Answer 5

Well in this case it will be m/s^2=N/kg

Answer 6

What is 90000000/3000000?

Answer 7

/=Divided

Answer 8

George?

Answer 9

30

Answer 10

Alrighty.

Answer 11

So that would mean...

Answer 12

30m/s^2=90000000N/3000000kg

Answer 13

For number one.

Answer 14

That's the answer?

Answer 15

Noo.

Answer 16

Oh ok

Answer 17

Is it the weight u tryna calculate?

Answer 18

"The mass of the rocket is 3000000kg"

Answer 19

which equals to 6613867.866 pounds

Answer 20

Hmm ok

Answer 21

What formula did u use
