Two balls are dropped from different heights at different instants. Seconds ball is dropped 2 sec. after the first ball. If both balls reach the ground simultaneousl after 5 sec. of dropping the first ball. then the difference of initial heights of the two balls will be :- `(g=9.8m//s^(2))`

Text Solution

Verified by Experts

The correct Answer is:
`1/t^(2)`

`a_(t)=ar, alphar=omega^(2)r, alpha=alpha^(2)t^(@)rArr alpha=1/t^(2)`
