Under the influence of its drive force, a snowmobile is moving at 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 138 kg. Under the influence of a drive force of 195 N, it is moving at a constant velocity whose magnitude is 6.13 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.
