Math Problem Statement
Solution
To find the launch angle required for the cyclist to reach a maximum height of 35 feet above the landing zone, we need to analyze the maximum height in the vertical motion of the cyclist. Here’s how to approach it:
Step-by-Step Solution
-
Vertical Motion Equation: The height function given is:
-
Maximum Height Condition: The maximum height is achieved when the vertical velocity is zero. The vertical velocity function is: Setting to find the time at maximum height:
-
Substitute Back into : Substitute into to find the maximum height:
-
Set Maximum Height to 35 Feet: Now, we set this expression equal to 35 and solve for :
This is a quadratic equation in terms of , and solving this equation will give us the required value of to reach a maximum height of 35 feet.

Here are five related questions for further exploration:
- What would be the launch angle if the maximum height required were different, say 40 feet?
- How would changes in the cyclist's initial speed affect the parametric equations?
- What is the total horizontal distance traveled by the cyclist?
- At what angle should the ramp be inclined to maximize the horizontal distance of the jump?
- How long does it take for the cyclist to reach the maximum height?
Tip: In projectile motion problems, analyzing horizontal and vertical motions separately often simplifies calculations.
