Over a time interval of 2.06 years, the velocity of a planet orbiting a distant star reverses direction, changing from +22.7 km/s to -22.1 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s2) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration. (a) Number Units (b) Number Units
