1H10.11 Reaction Cart

All the things you can do standing and running on carts with and without ropes.

 

In this photo, we see a sturdily-built four-wheeled cart that is at least eight feet long and quite narrow for its length. Its top surface is smooth and black. Its weight has to be felt to be believed.

 

A person starting on the floor may jump on the cart. The cart moves, of course, in the direction of his original motion.

 

A person standing on a cart at rest may start to run along it. The cart moves in the opposite direction.

 

A person walking at constant speed may, walk along a cart without moving it. Since there is no transfer of momentum his speed is constant.
