Answer:
The acceleration of the rocket is 10 m/s².
Step-by-step explanation:
Let the acceleration of the rocket be
m/s².
Given:
Mass of the rocket is,

Thrust force acting upward is,

Acceleration due to gravity is,

Now, force acting in the downward direction is due to the weight of the rocket and is given as:

Now, net force acting on the rocket in upward direction is given as:

Therefore, from Newton's second law, net force acting on the rocket is equal to the product of mass and acceleration.

Therefore, the acceleration of the rocket is 10 m/s².
