2D Kinematics
A satellite in outer space is moving at a constant velocity of 20.6 m/s in the +y direction when one of its onboard thruster turns on, causing an acceleration of 0.400 m/s2 in the +x direction. The acceleration lasts for 46.0 s, at which point the thruster turns off.(a) What is the magnitude of the satellite's velocity when the thruster turns off?
Answer
Greetings,
I see you have a question about the 2-D motion of a satellite. When thinking about 2-D motion, it is best to start by writing down the components of the acceleration during the motion and anything we know about the components of the velocity and displacement at the initial and final points of the motion that we are considering. Drawing a little picture of the motion is also good at the start of a problem so that we can visualize what is happening more clearly. Once we have a good idea of what we have been told about the motion, we can use our 2-D kinematic equations to try to figure out the parts of the motion that we weren't told about. Remember, the 2-D kinematic equations can be used just like the 1-D kinematic equations but it is important to treat the x-components and the y-components separately.
After trying that, are there any specific places where you are stuck with this problem or things that you don't understand about it?
