Question

A toy rocket of mass 4.00 kg accelerates upwards at 7.00 m/s2. Calculate the thrust force of the rocket

Answer 1

Given data:

* The mass of the toy rocket is m = 4 kg.

* The acceleration of the rocket is,

$a=7ms^{-2}$

Solution:

According to Newton's second law, the thrust force of the rocket is,

$\begin{gathered} F=ma \\ F=4\times7 \\ F=28\text{ N} \end{gathered}$

Thus, the thrust force of the rocket is 28 N.
