Question by : Using energy conservation to find the maximum height?
A 65.0 kg skier approaches the foot of a hill with a speed of 16.0 m/s. The surface of this hill slopes up at 55.0 degrees above the horizontal and has coefficients of static and kinetic friction of 0.750 and 0.250, respectively, with the skis.

Use energy conservation to find the maximum height above the foot of the hill that the skier will reach.

Best answer:

Answer by TBT
initial KE
= 0.5 * 65 * 16^2 J

let h be the maximum height above the foot of the hill that the skier will reach

normal force due to weight
= 65 *g * cos 55
friction force
= 0.25 * 65 *g * cos 55
length travelled
= h /sin 55

final PE + work done due to friction
= 65 * g * h +0.25 * 65 *g * cos 55 * h /sin 55

65 * 9.81 * h + 0.25 * 65 *9.81 * cos 55 * h /sin 55 = 0.5 * 65 * 16^2
637.65 h + 111.59 h = 8320
h = 11.1 m —answer

Fundamentals of Physics, II (PHYS 201) The law of conservation of energy is reviewed using examples drawn from Newtonian mechanics. The work-energy theorem is derived from first principles and used to initiate a discussion of the vector calculus underlying the law of conservation of energy. Complete course materials are available at the Open Yale Courses website: open.yale.edu This course was recorded in Spring 2010.

Visit EnlightenVa.org to help bring Virginia out of the energy Dark Ages! Local residents of Fauquier and Prince William Counties discuss one simple change we can all make to reduce our energy consumption. Compact florescent bulbs use a quarter of the energy of a traditional incandescent light bulb. That helps your pocket book and the environment too! This ad is in response to Dominion Power’s plans to construct a new 500 kilovolt transmission line through the Shenandoah Valley and Northern Piedmont region of Virginia. Local organizations and county governments affected by the line have passed resolutions in opposition to Dominion’s Power’s plan, stating that we should conserve energy first before condemning people’s private property. Changing our light bulbs is just one simple first step you can take to make a difference. The second step you can take is to contact Governor Tim Kaine at (804) 786-2211 and tell him to make energy conservation a priority in Virginia. Act Now!

I need assistance in figuring out this problem: A 0.40 kg ball is thrown with a speed of 12 m/s at an angle of 33 degrees. a)What is its speed at its highest point? and b) how high does it go? (Use conservation of energy, and ignore air resistance.)

(For part a) I’m guessing that the conservation of energy equation doesn’t apply because there is no vertical velocity and only horizontal velocity, which would be 12 * cos 33 degrees)

Thanks!
