The answer would be stay because the surface is flat so it will stay!
The x-acis of a trajectory represents its C
400m in 32sec: (400/32)>12.5meters per second>
(12.5)(60)(60)(1/1000)=45km per hour
Constant speed would mean that the two forces are equivalent
The volume decreases, by a factor of
(the original pressure/(125 kPa).
