Textbook Question
Textbook QuestionA “doomsday” asteroid with a mass of 2.0 x 10¹⁰ kg is hurtling through space. Unless the asteroid’s speed is changed by about 0.20cm/s , it will collide with Earth and cause tremendous damage. Researchers suggest that a small “space tug” sent to the asteroid’s surface could exert a gentle constant force of 2.5 N. For how long must this force act?
