Chapter 5, Problem 79PP
A spiral is an ice-skating position in which the skater glides on one foot with the other foot held above hip level. It’s a required element in women’s singles figure skating competition and is related to the arabesque performed in ballet. Figure 5.40 shows skater Sarah Hughes executing a spiral during her gold-medal performance at the Winter Olympics in Salt Lake City.
FIGURE 5.40 Problem 77-80
If the skater were to execute the same maneuver but at higher speed, the tilt evident in the photo would be
- a. less.
- b. greater.
- c. unchanged.

There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s2. Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier. Express your answer numerically, in meters per second.arrow_forward
