In situation 2, only one of the astronauts pushing, the force is halved, the initial energy is reduced by a factor of 2, and the final velocity is reduced by a factor of 2, which comes from the energy law: M v 2 = k x 2 2. Next, consider situation 3. Here the two plates are attached to each other.
WebAs they stand up taller, their skating stride shortens, they produce less push-off force with each stride, and they slow down. Secondly, speed is largely determined by how much force a player can put into the ice with each stride. The more force that pushes into the ice, the further the player is propelled forward.
