Which rocket has the highest acceleration?

A. Rocket 3

B. Rocket 1

C. Rocket 4

D. Rocket 2

Answer 1

In the given four models of rockets, the rocket with the highest acceleration is rocket 2.

Acceleration of the rockets

Acceleration is the rate of change of velocity with time. The acceleration of the rockets can also be determined from Newton's second law of motion with the applied force and mass of each rocket as shown below;

F = ma

where;

• F is the applied force
• m is the mass
• a is the acceleration

a = F/m

Rocket 1

a = 120/4.25

a = 28.24 m/s²

Rocket 2

a = 120/3.25

a = 36.92 m/s²

Rocket 3

a = 120/5.5

a = 21.82 m/s²

Rocket 4

a = 120/4.5

a = 26.7 m/s²

Thus, the rocket with the highest acceleration is rocket 2.
