An airplane flies in a semi-circular arc in order to simulate "weightlessness" for its occupants. If the radius of the semicircular path it flies is 3500 m, what is the speed at which the plane flies?
Added by William C.
Step 1
Weightlessness occurs when an object is in freefall and experiences zero gravity. In this case, the airplane is flying in a semi-circular arc, which means it is constantly changing direction and experiencing a centripetal force that keeps it in the circular Show more…

A supersonic airplane is flying horizontally at a speed of 2540 km/h. What is the centripetal acceleration of the airplane, if it turns from North to East on a circular path with a radius of 70.0 km? How much time does the turn take? How much distance does the airplane cover during the turn?
