Under the influence of its drive force, a snowmobile is movingat a constant velocity along a horizontal patch of snow. When thedrive force is shut off, the snowmobile coasts to a halt. Thesnowmobile and its rider have a mass of 125 kg. Underthe influence of a drive force of 205 N, it is movingat a constant velocity whose magnitude is 5.47 m/s.The drive force is then shut off. Find
(a) the distance in which the snowmobile coasts to a halt and
(b) the time required to do so.
