Astronauts use a centrifuge to simulate the acceleration of a rocket launch. the centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.20 s. the astronaut is strapped into a seat 4.00 m from the axis.

what is the astronaut's tangential acceleration during the first 40.0 s?

how many g's of acceleration does the astronaut experience when the device is rotating at top speed? each 9.80 m/s^2 of acceleration is 1 g.

The force will determine the acceleration.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
