SUMMARY

The discussion focuses on a projectile motion problem involving a skateboarder launching off a ramp with an initial velocity of 5.1 m/s at an angle of 58° above the horizontal. The ramp's height is 1.4 m, establishing the skateboarder's initial vertical position (y0) at 1.4 m. The key points of confusion addressed include the interpretation of the coordinate system, specifically that the origin is set at ground level directly below the ramp's top, meaning the ramp's end is 1.4 m above this origin.

PREREQUISITES
  • Understanding of projectile motion principles
  • Knowledge of kinematic equations
  • Familiarity with trigonometric functions for angle calculations
  • Ability to interpret coordinate systems in physics
NEXT STEPS
  • Calculate the maximum height reached by the skateboarder using kinematic equations
  • Determine the horizontal distance traveled at the highest point using projectile motion formulas
  • Explore the effects of different launch angles on projectile motion
  • Study the concept of energy conservation in projectile motion scenarios
USEFUL FOR

Students studying physics, particularly those focusing on kinematics and projectile motion, as well as educators looking for examples to illustrate these concepts.

Homework Statement



A skateboarder shoots off a ramp with a velocity of 5.1 m/s, directed at an angle of 58° above the horizontal. The end of the ramp is 1.4 m above the ground. Let the x-axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp.
(a) How high above the ground is the highest point that the skateboarder reaches?
(b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?


Before I even start doing the problem, I would have to know how the figure looks like so that I can draw it out on my paper, but I'm having troubles. I don't understand the part "take as the origin the point on the ground directly below the top of the ramp".
Does it mean that the top(highest point) of the ramp is exactly at the origin? or does it mean that ground is 1.4m below the origin? Please help...

It means that the end of the ramp is vertically 1.4 m above the origin, so the skateboarder's initial vertical position y0 is 1.4 m.
