Question 2

A model rocket of mass 500 g is launched vertically upwards. During the initial stage of its launch, the rocket's engine produces a constant vertical thrust of 15 N. The rocket experiences a constant air resistance of 2.1 N.

Taking g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2, find the acceleration of the rocket.
