A 25.0-g ice cube is set sliding around the cone without friction in a horizontal circle of radius R. (a) Find the speed the ice cube must have as a function of R. (b) Is any piece of data unnecessary for the solution? Suppose R is made two times larger. (c) Will the required speed increase, decrease, or stay constant? If it changes, by what factor? (d) Will the time interval required for each revolution increase, decrease, or stay constant? If it changes, by what factor? (e) Do the answers to parts (c) and (d) seem contradictory ? Explain.

Problem 69. A block of mass m starts from rest at the top of an incline. The block starts at a height of H above ground
level and the angle of the incline is 0. Set up, and solve symbolically, an equation to determine the speed at the bottom of
the incline if the coefficient of kinetic friction between the block and the incline is uK.
A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally.
As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.418 s after leaving the slide. Ignore
friction and air resistance, find the height H in the drawing.

In a "crazy elevator ride" at the amusement park, a 300 kg "elevator car" slides vertically down a frictionless shaft and curves onto a horizontal section, descending a total height of 25 m. On the horizontal section is a friction pad designed to bring the car to rest. If the coefficient of friction between the car and the pad is μk=0.4, how long in meters does the pad need to be to stop the car?

- A student is asked to measure the acceleration of a glider on a frictionless, inclined plane, using an air track, a stopwatch, and a meterstick. The top of the track is measured to be 1.774 cm higher than the bottom of the track, and the length of the track is d = 127.1 cm. The cart is released from rest at the top of the incline, taken as x = 0, and its position x along the incline is measured as a function of time. For x values of 10.0 cm, 20.0 cm, 35.0 cm, 50.0 cm, 75.0 cm, and 100 cm, the measured times at which these positions are reached (averaged over five runs) are 1.02 s, 1.53 s, 2.01 s, 2.64 s, 3.30 s, and 3.75 s, respectively. (a) Construct a graph of x versus t2, with a best-fit straight line to describe the data. (b) Determine the acceleration of the cart from the slope of this graph.
