During the first 10 seconds of a rocket launch, the momentum of the rocket increased by 8000 kg*m/s. what was the impulse applied to the rocket during this time?

I = 8000 kg*m/s

Explanation:

given,                                                      

time interval = 10 sec                                      

momentum of the rocket is increased by = 8000 kg*m/s

Impulse applied = ?                                              

Impulse is equal to the change in momentum of the object.

Impulse is defined as the change in momentum of the body due to the force acting on the body for an instant of time.

In the question change of momentum is given as  8000 kg*m/s

So, the impulse applied during the interval of time will be equal to

          I = 8000 kg*m/s

Explanation:

In multiplications or divisions, the result must be written using a number of significant figures equal to the smallest number of significant figures contained in the original numbers.

For instance, in this case the two numbers are:

3278 --> 4 significant figures

42 --> 2 significant figures

So, the product must be written using 2 significant  figures.

Calculating the product, we get:

Therefore, using 2 significant figures only, the result is
