Question

The Mars Global Surveyor orbits Mars at an average altitude of 405 km. The average radius of Mars is 3390 km. If it takes the spacecraft 1.95 hours to complete one orbit around the planet, what is it's tangential velocity in kilometers per hour?

b) In the activity problem, if the spacecraft's tangential velocity slows down to 10,000 kilometers per hour over a time of 6 minutes, what is the angular acceleration(deceleration) in units of radians per hour squared? Please enter your answer as a positive number with 2 decimal places and no units.gb

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
