Given data:
* The mass of the toy rocket is m = 4 kg.
* The acceleration of the rocket is,
[tex]a=7ms^{-2}[/tex]Solution:
According to Newton's second law, the thrust force of the rocket is,
[tex]\begin{gathered} F=ma \\ F=4\times7 \\ F=28\text{ N} \end{gathered}[/tex]Thus, the thrust force of the rocket is 28 N.
