Under the influence of its drive force, a snowmobile is movingat a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 149 kg. Underthe influence of a drive force of 195 N, it is movingat a constant velocity whose magnitude is 5.61 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.
