This may not be the conventional way of serving a tennis ball but it’s a great application of conservation of momentum.

Dreadnoughtus was a herbivore and likely spent most of its day eating huge quantities of plants just to keep up its massive bulk. Dreadnoughtus also had a long muscular tail that could sweep away predators in one powerful swipe.
