10. (10 points) A skier is traveling at 25 m/s when they begin going up a hill that makes an angle of 30° with respect to the horizontal. The coefficient of kinetic friction between their skis and the slope is 0.10 and we are interested in how far they travel up the hill. How far up the slope (d) do they travel before coming to rest?

15. A 59.0-kg boy and his 42.0-kg sister, both wearing roller blades, face each other at rest. The girl pushes the boy hard, sending him backward with a velocity 3.00 m/s toward the west. Ignore friction. (a) Describe the subsequent motion of the girl. - She will move east, directly away from her brother with a speed 5.71 m/s. - She will move east, directly away from her brother with a speed 1.5 m/s. - She will move east, directly away from her brother with a speed 4.21 m/s. - She will move west, in the same direction as her brother, with a speed 3.00 m/s.
