A spacecraft drifts through space at a constant velocity of 5 km/s. It then turns on a jet that provides a constant force in the direction perpendicular to the direction of its initial velocity. Afterthe jet turns on, how long does it take for the component of the spacecraft's position along the direction of its initial velocity to change by 1000 km? If there is not enough information given to answer the question, explain what information is missing and how you would use it to answer the question.
