Question

26. A body thrown vertically up with a velocity u reaches the maximum height h after
T second. Correct statement among the following is
(A) At a height h/2 from the ground its velocity is u/2
(B) At a time Tits velocity is u
(C) At a time 2T its velocity is -u
(D) At a time 2T its velocity is -6u
(E) None of these

Answer 1

Answer:

Option(C)

Explanation:

Given Initial velocity = u , maximum height= h,

At maximum height, final velocity = 0,

∴ v = u - gT

=> 0 = u - gT

=> T = u/g

Then,

∴ 2T = 2(u/g)

Velocity after 2T,

v = u - gT

=> v = u - g * (2u/g)

=> v = u - 2u

=> v = -u
