MY NOTES PRACTICE ANOTHER Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the "Holly hump") and had it installed. Suppose a 1800-kg car passes over a hump in a roadway that follows the arc of a circle of radius 18.0 m as in the figure below. (a) If the car travels at 26.2 km/h what force does the road exert on the car as the car passes the highest point of the hump? magnitude N direction up (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point? km/h Need Help?

MY NOTES PRACTICE ANOTHER One end of a cord is fixed and a small 0.250-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 2.50 m as shown in the figure below. When 0 = 27.0, the speed of the object is 7.50 m/s. At this instant, find each of the following. (a) the tension in the cord N (b) the tangential and radial components of acceleration a. = m/s inward a, = m/s2 downward tangent to the circle (c) the total acceleration atotal = m/sz inward and below the cord at (d) Is your answer changed if the object is swinging down toward its lowest point instead of swinging up? Yes O No (e) Explain your answer to part (d)
