Question

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

Answer 1

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

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