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? )​
