SUMMARY

The discussion centers on calculating the initial speed of a Nordic jumper launching off a ski jump at a 10.0-degree angle below the horizontal. The jumper travels 108 meters horizontally and 55.0 meters vertically before landing. To solve this problem, participants recommend using kinematic equations for projectile motion, specifically separating the horizontal and vertical components of motion to derive the necessary speed at launch.

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Knowledge of projectile motion concepts
  • Ability to draw and interpret motion diagrams
  • Familiarity with trigonometric functions for angle calculations
NEXT STEPS
  • Study the kinematic equations for projectile motion
  • Learn how to decompose motion into horizontal and vertical components
  • Research the effects of angles on projectile trajectories
  • Explore practical applications of projectile motion in sports physics
USEFUL FOR

Students studying physics, educators teaching projectile motion, and athletes interested in optimizing performance through understanding motion dynamics.

Homework Statement



A Nordic jumper goes off a ski jump at an angle of 10.0 degrees below the horizontal, traveling 108 meters horizontally and 55.0 meters vertically before landing. (a) ignoring friction and aerodynamic effects, calculate the speed needed by the skier on leaving the ramp.

I don't know where to start :(

start by drawing a diagram. Then can you write the horizontal and vertical equations?
