v P rt A You go to the playground and slide down the slide. a a 4.0-m-long ramp at an angle of 36. with respect to horizontal. The pants that you've worn _ _ aren't very slippery; the coefficient of kinetic friction How long does It take you to reach the bottom of the slide? between your pants and the slide is pk = 0.43. A friend gives you a very slight push to get you started. Express your answer with the appropriate units. t= i Value Units nest Answer Two horizontal curves on a bobsled run are banked at the same angle, but one has twice the radius of the other. The safe speed (for which no friction is needed to stay on the run) for the smaller radius curve is 1/. What is the safe speed on the larger-radius curve? V12
