The skiing duo of Brian (83 ) and Ashley (46 ) is always a crowd pleaser. In one routine, Brian, wearing wood skis, starts at the top of a 280 long, 20 slope. Ashley waits for him halfway down. As he skis past, she leaps into his arms and he carries her the rest of the way down. Hint: Use coefficient of kinetic friction from the textbook.
What is their speed at the bottom of the slope?
