Question

An astronaut is bored, and decides to fly his rocket at constant speed in a perfect circle in deep space, far away from any planets or stars (safety first). The rocket has mass 6.50e7 kg, the circle has radius 15 km, and the speed of the rocket is 5000 m/s in its path along the circle. (a) What is the force of the engines on the rocket (the thrust) while the rocket flies the circle? N( + 8E7 N) (b) The diagram below shows the circle the ship follows along with 4 points labeled A, B, C, and D during the rocket's motion. The rocket is shown at point A, but the direction that the rocket is pointed in the figure is not necessarily the direction it would need to be pointed at that position. A η Which direction should it point?

Sketch the circle on your written homework and on your sketch show how the rocket must be oriented at each of the 4 labeled points. The thrust vector (i.e. net force vector on the rocket) of the rocket always points directy from the flames to the pointy-end. At each point:

• Clearly show which way the front end of the rocket points and also clearly show which end of the rocket has the rocket engine.
• Indicate whether the engine is firing, or not.

I think the rocket is already in the air flying from how the question is asked/worded
