# What thrust does a model rocket need in order to have a vertical acceleration of a. On earth? b. On the moon, where g = ?

a. Acceleration due to gravity on Earth is

b. Acceleration due to gravity on Moon is

See the step by step solution

## Step 1: Content Introduction

We have the forces acting on the rocket and we are given,

Mass of the model rocket

vertical acceleration

Apply Newton's second law to calculate the thrust of the rocket.

## Step 2: Explanation (Part a)

Acceleration due to gravity on Earth , ,is the mass, is the vertical acceleration

By substituting numerical numbers in equation, the thrust on the rocket is computed.

## Step 3: Explanation (Part b)

Acceleration due to gravity on Moon ,

By substituting numerical numbers in equation, the thrust on the rocket is computed.
