John and Abdallah stand on a playground round about at distance 1meter and 1.5 meter respectively from the circle of rotation. If the round about revolve at 12rev/min. Find the speed which John and Abdallah are moving.​

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
