For Newton's second law, the force is equal to the product between the mass and the acceleration of the rocket:
From which we can rewrite the acceleration as
where m=7.0 kg.
The velocity of the rocket is the derivative of the acceleration:
and if we substitute x=9.0 m, we find the rocket velocity after 9.0 m:
Answer:
For example, a wave with a time period of 2 seconds has a frequency of
1 ÷ 2 = 0.5 Hz.
