Chapter 12.1, Problem 12.5P
In anticipation of a ling 7° upgrade, a bus driver accelerates at a constant rate of 3 ft/s2 while still on a level section to the highway. Knowing that the speed of the bus is 60 mi/h as it begins to climb the grade and that the driver does not change the setting of his throttle or shift gears, determine the distance traveled by the bus up the grade when its speed has decreased to 50 mi/h.

Cardo Dalisay is pushing a loaded sled across a level field of ice at the constant speed
of 10 ft./sec. When the man in halfway across the ice field, he stops pushing and lets
the loaded sled continue on. The combine weight of the sled and its load is 80lb; the
air resistance (in Ib) is numerically equal to 3v/4, where v is the velocity of the sled (in
feet per second); and the coefficient of fraction of the runners on the ice is 0.04. How
far will the sled continue to move after Cardo stop pushing?
A girl rolls a ball up an incline and allows it to return to her. For the angle and ball involved, the acceleration of the ball along the incline is constant at 0.34g, directed down the incline where g is the gravitational acceleration. If the ball is released with a speed of 4.2 m/s, determine the total time (s) required for the ball to return to the child’s hand. . Round off only on final answer expressed in three decimal places.
