Question

A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 140 m/s and it is accelerating at 20 m/s2 . At this instant, the rocket's mass is 51 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?

Answer 1

The net force on the rocket is 1020 N.

Step-by-step explanation:

The net force on the rocket can be calculated using Newton's second law, which states that the net force acting on an object is equal to its mass multiplied by its acceleration. In this case, the acceleration of the rocket is given as 20 m/s² and the mass is given as 51 kg. Therefore, the net force on the rocket can be calculated as:

F = m * a
F = 51 kg * 20 m/s²
F = 1020 N

So, the net force on the rocket is 1020 N.

Answer 2

Step-by-step explanation:

The force will be 98 N....
