You go to the playground and slide down the slide, a 3.0 meter long ramp at an angle of 36 degrees with respect to horizontal. The pants that you've worn aren't very slippery; the coefficient of kinetic friction between your pants and the slide is 0.43. A friend gives you a very slight push to get you started.

How long does it take you to reach the bottom of the slide?
