A stone projected at angle `53^(@)` attains maximum height 25m during its motion in air. Then its distance from the point of projection where it will fall is

A

75m

B

`400/3 m`

C

`50 m`

D

`60 m`

Text Solution

Verified by Experts

The correct Answer is:
A
velocity of projectile `=(50sqrt(5))/4 m//s` (by appling equation `v^(2)=u^(2)+2as` in vertical direction )
time of flight `=(8v)/(5g)`
distance travelled `=v cos 53^(@) xxT=3/5 v xx8/5 v/g=75 m` (by putting the value of v )
