Question

Two bodies are made to fall from two different heights in the ratio 9: 4. What will be the ratio of the time of fall?

Answer 1

Answer:

Let the two bodies fall from heights H and h, such that H>h. Now for a body dropped from height H and falling freely itsvelocity V on reaching the ground is

V²= 2 g H,……..1

For the body dropped from height h and falling freely, its velocity v, on reaching the ground is,

v² = 2 g h,

Now V/v = 4/3, (given)or V²/v² = 16/9,

Now

H/h = V²/v² = 16/9.

Therefore the two heights are in the ratio of 16:9.
