HEWITT DREW IT

32. Energy of Acrobats 

A problem solution, nicely simplified, to acrobats Ari, Bari, and their dog Bo.

End Question:

If Ari is replaced with circus dog Bo, who has one-fifth the mass of Bart, and the Bo’s trainer is positioned 20 m high for a hoped-for catch, will Bo’s propulsion be enough to reach the trainer?
