so guys im doing a project for my math class and i could choose anything in relation to math, so of course i picked skiing. so basically i need help in coming up with grade 11 topics in relation to skiing. help me pleaseee, thanks.

google projectile motion. They'll give you a bunch of equations for telling how far something will go depending on the launch angle and velocity.

Force of friction while grinding.  Terminal velocity/air resistance.  Acceleration of gravity given a slope with an angle.  And projectile motion, of course.

word, angle of jumps. they could make right triangles and there u go

maximum velocity when jumping off the chair, what is the safest hight to do so? how much speed to clear gaps? coefficiant of steeze? probability of getting another skiers phone number on a chair ride?

spins as angles and shit. uhhh maybe like an equation for distance, speen or sumthing else

yeah you could do how much speed to clear gaps, and like how big of a jump and angle, and do cool gaps like chad's and pyramid

do something about centrifugal force and spinning if that works

man all yo uguys are talking physics. she needs math. do something easy like the total cost of someones gear. make a scatterplot of the cost of peoples geat cost and then on a TI-83 find the line of best fit for an avergae...now theres an idea

heres a problem my dad put in one of his books he wrote. Its might not be hard enough depending on what math class you are in.

assuming a flat lip like /  (of course this jump would blow) find the height of the jump if its 10 feet long and the takeoff is 15 feet long. if you do a 900, what is this angle in radians. convert 180 cm skis into inches or feet. eh, pretty basic, but its all i could come up with.

you cannot ski on an undefined slope (90 degrees...adjacent to the x axis)....nor can you ski on a zero slope ( 0 degrees...adjacent to the y axis) ...this pretty much means nothing, but i learnt it last year in gr.10 math...i cant think of gr.11 math having to do anything with skiing

so what is grade 11 math? In 11th grade I took calculus and a lot of people took trigonometry.

I've done something like that where we've taken 5 different jumps (step-up, step-down, table, booter and gap) of 3 different sizes (30, 60, 90) and we calculated the speed needed to barely clear, to almost overshoot, and to land perfectly, then we calculated the amount of force you would hit with if you undershot/overshot, and figured out which jumps had the largest chance of failure and which had the worst fall scenarios.

make a quadratic function relating your height off a jump or halfpipe to your speed. that would be sweet. parabolas rule.

Here's a page with some really basic info on the physics of skiing.
