Funny email received with Physics PE problem

[lynk]

Hello,

I recently got a "joke" email with this problem in it.
The student drew an elephant in the middle of the ramp & answered "b" with: No, there is an elephant in the way.
It is relevant to my current studies, so I worked it out and would like to know if I am correct.
Please see attachment.

My answer for "a" is x=1.69m and for "b," Yes, and it will reach 5m again, because the ramp is frictionless.
Are my answers correct or did I miss something?

Enjoy the humorous j-peg.

Thank you,
Lynn

Hello Lynn!

Yes, your answers are fine.

(but how did your student manage to sneak the elephant past the elephant-detectors into the exam room? )​

Dear Lynn,

Thank you for sharing this funny email with me. It's always nice to see humor in the world of science and physics. As for your answers, they are indeed correct. Your calculation for the distance of the elephant on the ramp (x=1.69m) is accurate and your reasoning for why the ball will reach 5m again (due to the frictionless ramp) is sound. Keep up the good work in your studies and always remember to find joy and humor in your scientific pursuits.
