A waterslide ride consists of a straight guided ramp, at an angle(to the horizontal plane), with a transition to a short horizontal section at the bottom of the slide (1m long), just above the surface of a splace pool of lengththeta. Patrons queue on a platform of heightL(edge of platform is 18m from start of horizontal section of slide) before climbing onto a 10kg toboggan and sliding down slide under the force of gravity until they leave the slide and skip along surface of splash pool.h

Water slide is lubricated by 12L/s of water

When= 53degreestheta

= 7.6mh

1. Determine Rider speed

2. and stopping distance if;

average weight of rider is 100kg and toboggan is 10kg

coefficient of friction between toboggan and slide (

) is;us

0.2 (Q 20)/50 (Where Q is in L/s)

coefficient of friction between toboggan and pool water

is;uw

0.6

****Taking into account dynamic friction only*****

3. Determine length of splash pool neededL

2. Relevant equations

3. The attempt at a solution

I have been trying to figure this out using various equations, none of which seems correct... someone please help guide me onto the right track?!

I think i need to use the equation a= netforce / mass = g(sin theta - cos theta)

then use the formula V(final)^2 = V(initial)^2 + 2 as

to find net force I just used netforce= mass x g <<<<<<< I think this is incorrect because I am supposed to factor in the angle?! but how?

then use formula Stopping distance (D) = (V(final)^2 / 2x us x g) - (V(final)^2 / 2x uw x g)

i cannot figure out where to use the flow rate in this at all... i think i have totally stuffed up.... i really need help
