Question

Calculate the force that is needed to propel a rocket into space if the rocket weighs 10,000 kg and the escape velocity for Earth’s gravity is 11 km/s. (Hint: use the formula F ma).

Answer 1

Therefore, the force needed to propel the rocket into space is 110,000,000 N.

Step-by-step explanation:

To calculate the force needed to propel a rocket into space, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F=ma). The force required to propel the rocket into space is equal to the mass of the rocket multiplied by the acceleration needed to reach escape velocity.

Given that the mass of the rocket is 10,000 kg and the escape velocity is 11 km/s, we need to convert the escape velocity to m/s and then calculate the acceleration. 1 km/s is equal to 1000 m/s, so 11 km/s is equal to 11,000 m/s.

Using the formula F=ma, the force required is equal to 10,000 kg multiplied by the acceleration, which is 11,000 m/s. Therefore, the force needed to propel the rocket into space is 110,000,000 N.
