A body when projected vertically up, covers a total distance D during its time of flight. If there were no gravity, the distance covered by it during the same time is equal to :

Text Solution

Verified by Experts

The displacement of the body during the time t as it attains the point of projection
`rArr S = 0 `
`rArr v_(0)t-1/2"gt"^(2)=0`
`rArr t=(2v_(0))/g`
Dring the same time t, the body moves in absence of gravity through a distance
`D.=v_(0)t,` because in absence of gravety g=0
`rArr D. =v_(0)((2v_(0))/g)=(2v_(0)^(2))/g`
In presence of gravity the total distance covered is `=D=2H=2(v_(0)^(2))/(2g)=(v_(0)^(2))/g
(1)-:(2)rArr D.=2D`
