YO BITCHES I GOT A PHYSICS PROBLEM WITH SKIING. I WAS SO EXCITED GOTTA SHARE IT WITH You. if u get the answer tell me!

A 65 kg skier starts from rest at a height of H = 20 m above the end of the ski-jump ramp (Figure 8-39). As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless.


Fig. 8-39
(a) What is the maximum height h of his jump above the end of the ramp?
m
(b) If he increased his weight by putting on a backpack, would h then be greater, less or, the same?

the same (I GOT THIS PART ITS THE SAME)
greater
less

i had the WORST physics teahcer in high school, whoa she was bad... she made me hate it forever, so I'm in business, and I will never have to deal with a question like this EVER.

Physics is cool..
I HATE TO F***ing do the math in it...
But like the same formula (well.. u have to insert wind and friction resistance) could calculate how high you would fly on a jump, see if you could clear that cork 720 We wished the skier in the problem would pull of..

Draw a force diagram.

solve for x.

i got 4.6 m, which is close to 4.41, so its probably just from a rounding difference
i didn't read everyone elses responses, do you need to show your work?

it is 4.41 m, and I didn't round.



Life is not a journey to the grave with the intention of
arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly
proclaiming...'Wow! What a ride!'
