Net forces

A swimmer races across the pool in a competition. What are the action reaction pair in this situation?

The force of the swimmer’s hands pushing on the water and the water pushing back on the

swimmer’s hand.

Two Sumo wrestlers push against each other in a match. At first, wrestler A gets pushed backwards two steps, but then they stop moving even though they are still pushing against each other. Why did this happen?

At first the forces are unbalanced, then wrestler B pushes with a greater force

until the forces are balanced.

A jogger runs a race. He passes markers every 100 yards. Over time, it takes him longer to reach the markers. What is his motion?

His speed is decreasing
