The acceleration of the swimmer can be calculated using Newton's second law: F = ma, where F is the force applied, m is the mass of the swimmer, and a is the acceleration. Rearranging the formula to solve for acceleration, we get a = F/m. Plugging in the values, a = 250 N / 70 kg = 3.57 m/s^2. So, the swimmer will accelerate at a rate of 3.57 m/s^2.
Oh, dude, upthrust, also known as buoyant force, is a contact force. It's like when you're chilling in a pool and the water pushes you up, totally making you feel lighter. So yeah, it's all about that contact with the fluid, man.

newton's third law is describing how movement occurs. EX. when you pull the water down your side using the breast stroke the water moves down toward your feet while you are propelled forward. action in this case would be you moving your arm in the water and the equal reaction is the water pushing back on you. opposite reaction is the reason that forward movement occurs.

Floaties lift you up because,well....,here's an example: you just finished your floaties,now you jump into your pool,and,then,you start to float up to the surface of the pool,because,the air in the floaties get stronger everytime you go deep into the water,the mass of the pool gets from super strong to super weak, bye!

Atcually it was Emily in the pool cause she is a swimmer and Ian did.

Swimming in a shallow pool can be more challenging because there is less water to work with, making it easier to hit the bottom or sides. a deep pool can provide more space to swim without those obstacles.
it depends how fast the swimmer is

The most common way is to stand 3/4 from the front of the block and wait for the swimmer to come. When the swimmer gets to the "T" at the end of the pool the swimmer on the block dives in over the swimmer in the water.
There's two parts to this: 1) Only "jump in" a pool that is approved for diving, and only where it's deep enough that you won't be injured (by hitting the pool bottom or side). 2) If there's a shallow end, there no reason a non-swimmer couldn't wade into the pool under supervision (by a swimmer who can rescue them if they get into trouble). I wouldn't recommend a non-swimmer "jump in" the deep end of a pool even with supervision.
A pool and a stop watch.
