A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 120 m/s and it is accelerating at 18 m/s2. At this instant, the rocket’s mass is 48 kg and it is losing mass at the rate of 0.50 kg/s as it burns fuel. What is the net force on the rocket? Hint: Newton’s second law was presented in a new form in this chapter.
Step 1 of 2</p>
We are required to calculate the net force on the rocket.
