SUMMARY

The discussion focuses on calculating the maximum height a toboggan reaches on a frictionless icy hill inclined at 29.0 degrees, starting with an initial speed of 12.0 m/s. The total work-energy principle is applied, where the work done equals the change in kinetic energy. The calculations yield a vertical height of 5.625 meters, derived from the initial horizontal velocity component of 10.5 m/s and the acceleration due to gravity of -9.8 m/s². The solution method includes drawing a free body diagram, applying Newton's second law, and using trigonometric relationships to find the vertical height.

PREREQUISITES
  • Understanding of the work-energy principle
  • Knowledge of Newton's second law (F=ma)
  • Familiarity with basic trigonometry
  • Ability to calculate kinetic energy (K=1/2mv²)
NEXT STEPS
  • Study the work-energy theorem in detail
  • Learn about free body diagrams and their applications in physics
  • Explore the concepts of inclined planes and their effects on motion
  • Investigate the relationship between velocity components and angles in projectile motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and energy conservation, as well as educators looking for practical examples of applying the work-energy principle in real-world scenarios.

Homework Statement


At the base of a frictionless icy hill that rises at 29.0deg above the horizontal, a toboggan has a speed of 12.0 m/s toward the hill. How high vertically above the base will it go before stopping?


Homework Equations


Wtot=K2-K1
K=1/2mv^2
K2=1/2mv^2=K1+Wtot


The Attempt at a Solution


Vx=12cos(29) = 10.5 m/s
vf^2-vi^2=2as
0-(10.5)^2=2(-9.8)s
s= 5.625

This is how i would do it:
1. draw an fbd of the toboggan
2. use f=ma to solve for a
3. solve for distance traveled on the hill
4. then you make a triangle, with the distance you found in 3) being the hypotenuse, solve for the vertical side, and that's how high it has travelled.
