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 139 kg. Under the influence of a drive force of 180 N, it is moving at a constant velocity whose magnitude is 5.43 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. (a) s= i (b) t= i

A boy shoves his stuffed toy zebra down a frictionless chute. It starts at a height of 1.49 m above the bottom of the chute with an initial speed of 1.87 m/s. The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with a coefficient of kinetic friction of 0.239. How far from the bottom of the chute does the toy zebra come to rest? Assume g = 9.81 m/s?.
If the motor exerts a constant force of 300 N on the cable, determine the speed (ft/s) of the 20-kg crate when it travels s = 10 m up the plane, starting from rest. The coefficient of kinetic friction between the crate and the plane is u = 0.3
An airplane starts from rest on the runway. The engines exert a constant force of 78.0 kN on the body of the plane (mass 9.20 × 104 kg) during takeoff. How far down the runway does the plane reach its takeoff speed of 52.7 m/s?
A loaded ore car has a mass of 950 kg and rolls on rails with negligible friction. It starts from rest and is pulled up a mine shaft by a cable connected to a winch. The shaft is inclined at 30.5° above the horizontal. The car accelerates uniformly to a speed of 2.05 m/s in 11.0 s and then continues at constant speed.
