If a ball is dropped from 64 feet high and reaches the groun

If a ball is dropped from 64 feet high and reaches the ground in 2 seconds how much does the ball weigh?

Solution

The weight if the ball cannot be determined ,

As the weight of the ball doesn\'t depend on anyparameter in the given condition as far ,

For a free falling body ,

The initial velocity is (u) = 0 ,

And hence the time taken by the ball to reach the ground only depends upon the gravitational force ,

Since any weight of the ball if it left from certain height it takes same time as the less weight ball takes to reach the ground.
