Mathcad Community Challenge May 2023 - Optimize Trajectory for Maximum Horizontal Distance

A ball with a mass of 1 kilogram is at the top of a frictionless ramp 10 meters above the ground. The ball rolls down the incline and launches from a height of 2 meters and an angle of 30 degrees above the ground.

(This picture was created in Creo.)

  1. Create a function that calculates the horizontal distance as a function of initial height, launch height, and launch angle.
  2. Calculate the horizontal distance the ball will land from the end of the ramp.
  3. Solve for the angle that will optimize the horizontal distance.
  4. How will the horizontal distance change if this were performed on the Moon instead of on the Earth’s surface? Assume the acceleration due to gravity on the Moon’s surface is 1/6 that of Earth.
  5. Use the Chart Component to depict how the horizontal landing distance changes as a function of angle.
  6. Use a 3D Plot to show how the horizontal landing distance changes as a function of ramp height and launch angle. Assume the ball starts at a height of 10 meters.

The worksheet should contain sufficient documentation to stand on its own; someone unfamiliar with the initial problem should be able to understand what is being calculated.

Good evening fellow friends of Mathcad Prime,

 

Please find my contribution in attachment (Mathcad Prime 9).

 

Kind regards,

Looks great. Is your launch height and landing site at the same level?

You're right: I've made a mistake and I'll correct this tonight...

Another one in Prime 9. Bit more compact. perhaps harder to follow:

Prime 9  - compact and perhaps harder to follow.

Reminder to y'all that there is less than a week left in May! It was definitely fun reading the discussion here. 🙂
And if you want to be part of the discussion in the write-up for this challenge in June, get your submission in before May ends!

And thanks for the blog write-up about this challenge! I hope other Mathcad users learn a lot from what the Community members have done here.


(And great job to those that submitted some really fabulous Mathcad Prime worksheets; we've also distributed the PTC Community badges for May 2023.)
