A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 120 mis and it i

s accelerating at 18 mis 2. 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?

The net force on the rocket is 864 N

Explanation:

The net force acting on the rocket can be calculated by using Newton's second law of motion, which states that:

F = ma

where

F is the net force on an object

m is the mass of the object

a is its acceleration

For the rocket in this problem, at a certain instant we have:

m = 48 kg

$a=18 m/s^2$

Therefore, the force on the rocket is

$F=(48)(18)=864 N$
