3. A sled carrying a child (combined mass 30 kg) is given a push and then allowed to slide down a hill that makes an angle 0 with the horizontal. If the sled's initial velocity is 5 m-s1, pointed downhill, and its coefficient of kinetic friction with the snowy hill is µk = 0.15, what is the minimum value of 0 for which the sled will continue moving downhill forever (assuming, of course, it doesn't run out of hill)? A. 8.5° B. 0.15° D. There is no minimum angle: The sled will eventually stop moving for any value of 0. E. There is no minimum angle: The sled will keep on moving forever for any value of 0.

A penguin slides at a constant velocity of 1.4 m/s down an icy incline. The incline slopes above the horizontal at an angle of 6.9?degrees. At the bottom of the incline, the penguin slides onto a horizontal patch of ice. The coefficient of kinetic friction between the penguin and the ice is the same for the incline as for the horizontal slope. How much time is required for the penguin to slide to a halt after entering the horizontal patch of ice?

The brakes on a big truck fail and it is forced to use a runaway truck lane. The lane is perfectly horizontal, and full of deep gravel, creating a coefficient of kinetic friction between the truck and the gravel of 0.80. The truck enters the lane at moving 35 m/s (about 80 mph). How far does the truck travel before it stops?
