Shin and Hana are having fun at a water park. They travel down the slides as shown above (with a somewhat vague representation of them), each of which start a distance h above the water. Who has the faster speed when reaching the bottom of the slide? It's impossible to know, since we don't know the exact curvature of each slide. They both have the same speed at the bottom. Hana Shin

Two children stand on a platform at the top of a curving slide next to a backyard swimming pool. At the same moment the smaller child hops off to jump straight down into the pool, the bigger child releases herself at the top of the frictionless slide.(i) Upon reaching the water, how does the kinetic energy of the smaller child compare with that of the larger child?It is greater.It is less.    The two energies are equal.(ii) Upon reaching the water, how does the speed of the smaller child compare with that of the larger child is?It is greater.It is less.    The two speeds are equal.(iii) During their motions from the platform to the water, how does the average acceleration of the smaller child compare with that of the larger child?It is greater.It is less.    The two accelerations are equal.

Abby and Lola dive from an overhang into the lake below.Abby simply drops straight down from the edge, but Lola takes a running start and jumps with an initial horizontal velocity of 25 m/s.Neither person experiences any significant air resistance.Just as they reach the lake belowGroup of answer choicesthe speed of Abby will always be 25 m/s larger than that of Lola.the speed of Abby is larger than that of Lola.they will both have the same speed.none of thesethe speed of Lola will always be 9.8 m/s larger than that of Abby.

Two skaters, each of mass 85 kg, approach each other along parallel paths separated by 5.5 m. They have equal and opposite velocities of 1.9 m/s. The first skater carries one end of a long pole with negligible mass, and the second skater grabs the other end of it as she passes; see the figure. Assume frictionless ice. Describe quantitatively the motion of the skaters after they have become connected by the pole. What is their angular speed?

Two skaters, each of mass 35 kg, approach each other along parallel paths separated by 3.6 m. They have equal and opposite velocities of 1.4 m/s. The first skater carries one end of a long pole with negligible mass, and the second skater grabs the other end of it as she passes. See Fig. 12-42. Assume frictionless ice.Figure 12-42(a) Describe quantitatively the motion of the skaters after they have become connected by the pole. m (radius) rad/s (angular speed)(b) By pulling on the pole, the skaters reduce their separation to 1.0 m. What is their angular speed then? rad/s(c) Calculate the kinetic energy of the system in (a) and (b). J (energy for system a) J (energy for system b)
