You're heading an international effort to save Earth from an asteroid heading toward us at 11 km/s. Your team mounts a rocket on the asteroid and fires it for 10 min, after which the asteroid is moving at 21 km/s at 32° to its original path. In a news conference, what do you report for the acceleration imparted to the asteroid? (Express your answers using two significant figures separated by a comma. Assume that the positive x-axis is in the direction of the initial motion of asteroid and y-axis is perpendicular to it.)
