How Do You Calculate Snow Projection Components on a Slope?

[BeckyStar678]

Homework Statement

a snow-covered ski slope makes an angle of 35 degrees with the horizontal. when a ski jumper plummets onto the hill, a parcel of splashed snow projects to a maximum position of 5 m at 20 degrees from the vertical in the uphill direction. find the components of its maximum position a.) parallel to the surface and b.) perpendicular to the surface.

Homework Equations

The Attempt at a Solution

would i just use a triangle with 20 degrees and 5 meters as the hypotenuse. then find the other two sides using trig and those two sides i find are the parallel and perpendicular sides

Hi BeckyStar678!

No … that would give you the components parallel and perpendicular to the ground.

Hint: you need to draw a right-angled triangle with sides parallel and perpendicular to the slope.
