Work and energy theorem question

Click For Summary
SUMMARY

The discussion centers on applying the Work-Energy Theorem to determine the distance a 73 kg skier slides up a hill inclined at 9.3 degrees before stopping, starting with an initial speed of 4.2 m/s. The relevant equations include W = ΔE and W = Fd, emphasizing the conservation of energy principle. The problem involves calculating the work done against gravitational potential energy as the skier ascends the incline. The absence of friction simplifies the calculations, allowing for a direct application of these equations.

PREREQUISITES
  • Understanding of the Work-Energy Theorem
  • Basic knowledge of gravitational potential energy
  • Familiarity with forces acting on an inclined plane

Homework Statement


a 73kg skier coasts up a hill inclined at 9.3 degrees to the horizontal. friction is negligible. Use the work and energy theorem to determine how far along the hill the skier slides before stopping, if the initial speed at the bottom is 4.2m/s


Homework Equations



w=ek ( i think)

The Attempt at a Solution



really don't understand this question (missed the first 2 days of a new unit and am pretty lost :/)

No worries - have you tried looking up "Work-Energy Theorem" online?

It's basically a conservation of energy problem, with a shortcut using W=ΔE and W=Fd.
