Questions

Please answer the questions below.

Attempt to dock the rocket to the green patch(Space Station). To do it safely, the spaceship must be stopped at the station. Once you have figured out a code, take a screenshot and upload it below.

After the rocket engine has been fired, what does the rocket do motion-wise? What law governs this motion?

Considering a real rocket: what laws govern its motion as it forces hot gas in one direction?

Note: the rocket loses gas/mass as it does this. Would this affect the motion? How?

Sketch the graph of the force of the left engine vs. time. Assume the force is constant throughout the firing. Take the firing time to be 5 seconds.

Note: Draw your sketch in the sketchpad below

Write out the impulse equation for the left engine firing for a time, t. Write out the impulse equation for the right engine firing for a time, t. Remember the direction matters in the equation!

Now, assume the rocket is moving at 4m/s to the right. The left engine is now fired, what is the resulting motion? If the mass is 5kg and the left engine applies a 1N force for 15 seconds, what will the final velocity be?

Now, assume the rocket is moving at 4m/s to the right. The right engine is now fired, what is the resulting motion? If the mass is 5kg and the left engine applies a 1N force for 15 seconds, what will the final velocity be?

Say you got the rocket to move and then come to a complete stop. What would be the sum of the impulses?

How would you get the rocket to accelerate up and to the right? Draw the force vectors on the rocket, include the resultant force and velocity vectors.
