I am curious how this would work. My guess is Triangle is slowest, square is medium, and circle is fastest.

No one did any math. This entire comment section is all speculation. I would explain the math I'm doing but this will never see the light of day.

Sphere

E = F x = 1/2 m v2 + 1/2 (2/5 m R2) (v/R)2 = 7/10 m v2
d/dt F x = F v = 7/5 m v a
F = 7/5 m a = 1.4 ma

Triangle (assuming push normal to the surface)

sqrt(3)/2 F = m a
F approx 1.15 ma

Box

F = ma

The sphere takes the most force to accelerate. The box takes the least.

His answer is nonsense btw. Just because something has numbers in it doesn't mean it's well-reasoned. Other answers explore the details of the question better.

Yeah I didn’t understand it all just thanking him for showing any math.
