SUMMARY
The net force acting on an 8.0 kg rocket, which experiences a thrust of 100 N and air resistance of 4.9 N, is calculated to be 95.1 N. This is derived from the equation F_net = thrust - air resistance, resulting in 100 N - 4.9 N = 95.1 N. Consequently, the rocket's acceleration is determined using the formula F = MA, yielding an acceleration of approximately 11.89 m/s² when applying the net force to the mass of the rocket.
