A rocket was launched and it now has an acceleration of 3m pers second squared upwards.the mass of the rocket is 5000kg.calculate the net force acting on the rocket and the upthrust exerted by the exhaust gases on the rocket.
F=ma
The downward force on the burning gases from the exhaust is equal to the upward force on the rocket
F=ma
=5000x3
=1500N
To calculate the net force acting on the rocket, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the mass of the rocket is given as 5000 kg and the acceleration is 3 m/s^2.
So, to find the net force acting on the rocket, we can use the equation:
F = m * a
F = 5000 kg * 3 m/s^2
F = 15000 N
Therefore, the net force acting on the rocket is 15000 Newtons.
Now, let's calculate the upthrust exerted by the exhaust gases on the rocket. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the action is the force exerted by the rocket's exhaust gases, and the reaction is the upthrust exerted on the rocket.
Since the rocket has an acceleration of 3 m/s^2 upwards, the force exerted by the exhaust gases must be equal to the net force acting on the rocket. Therefore, the upthrust exerted by the exhaust gases is also 15000 Newtons.
