They're the best aren't they?

Homework Statement Interesing... A spring (k=80n/m ) has an equilibrium length of 1.00m . The spring is compressed to a length of 0.50m and a mass of 2.1kg is placed at its free end on a frictionless slope which makes an angle of 41 degrees with respect to the horizontal. The spring is...

It's sin24*200=h Boom got it

So...=( 86N(200m) / 132s) + (80*9.8*200cos(24)/132)??

So insert that when trying to figure out power? P = FΔx / t + Δ(mgh)/Δt?? or P=Δ(mgh)/Δt??

Homework Statement Physics and Skiers and Rope and Hills? A 80 kg skier grips a moving rope that is powered by an engine and is pulled at constant speed to the top of a 24 degrees hill. The skier is pulled a distance x= 200m along the incline and it takes 2.2 min to reach the top of the...

God bless

-80(n/m)x^2 + 60(n/m^2)x^3?

:( :( :(

The problem is that its online homework and we don't actually learn or need this stuff in class. Any chance for last ditch answer?

Honestly I'm so lost and you're obviously much too smart for me so I guess I must find help elsewhere. Sorry for making you do all that work for nothing...

Then since they are opposite F(x) = -((160 N/m )x - (180 N/m2 )x2)

if x=.24 then F(x) = 28.032

It should be negative. But the problem here is that I'm in a calculus based physics class and have only taken the derivative sections of calculus and not the integral based parts. So is there anyway you could help me through this step by step?

Oh my gosh haha, I'm trying to find how much work is done by the athlete
