Answer:
Rocket 2 has highest acceleration.
Explanation:
Net force,
F = mass (m) × acceleration (a)
We have,
m₁ = 4.25 kg and F = 120 N
[tex]a_1=\dfrac{F_1}{m_1}\\\\a_1=\dfrac{120}{4.25}\\\\a_1=28.23\ m/s^2[/tex]
m₂ = 3.25 kg, F₂ = 120 N
[tex]a_2=\dfrac{F_2}{m_2}\\\\a_2=\dfrac{120}{3.25}\\\\a_2=36.92\ m/s^2[/tex]
m₃ = 5.5 kg, F₃ = 120 N
[tex]a_3=\dfrac{F_3}{m_3}\\\\a_3=\dfrac{120}{5.5}\\\\a_3=21.81\ m/s^2[/tex]
m₄ = 4.5 kg, F₄ = 120 N
[tex]a_4=\dfrac{F_4}{m_4}\\\\a_4=\dfrac{120}{4.5}\\\\a_4=26.66\ m/s^2[/tex]
Hence, it can be seen that the highest acceleration is of rocket 2.
