A “doomsday” asteroid with a mass of 1.0x1010 kg is hurtling through space. Unless the asteroid’s speed is changed by about 0.20 cm/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?
