Question

What if you drop a 30 kg object and a 10 kg object from a bridge at the same time which one will hit the water first

Answer 1

Both of them will hit the water at the same time.

Step-by-step explanation:

The time taken to hit the water is given by:

Let H be the height of the bridge.

`H=ut+(1)/(2)gt^(2)\\\\Initial\:Velocity=u=0\\\\H=(1)/(2)gt^(2)\\\\t=√(2gH)`

The time taken to hit the water does not depend on the weight of the object.

It only depends on the height of the bridge.

Since, both the objects are dropped from the same bridge, they will hit the water at the same time.
